New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Krzysztof Koczubik (ksysju) of Poland. He is a member of BOINC@Poland.

The AP24 was returned on 23 Feb 2009 13:37:03 UTC. It was found by an Intel C2Q Quad CPU Q9300 @ 2.50GHz running 64 bit Linux. It took about 12 minutes and 10 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 13785500104035967+1004314*23#*n for n=0..23. Credits are as follows:

Finder: Krzysztof Koczubik
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section of All known AP24 and AP25.

Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Pawel Stachowiak (stachu @ fiddex) of Poland. He is a member of BOINC@Poland.

The AP24 was returned on 5 Apr 2009 13:35:23 UTC. It was found by an Intel Pentium Dual CPU E2180 @ 2.00GHz running 32 bit Windows XP. It took about 34 minutes to process the WU (each WU tests 3 progression differences).

The progression is written as 6274259724784693+2522655*23#*n for n=0..23. Credits are as follows:

Finder: Pawel Stachowiak
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section of All known AP24 and AP25.

Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 19898154930924749 surpassing the old record of 19516877252820799. The finder is Pawel Stachowiak (stachu @ fiddex) of Poland. This is his 2nd AP24 discovery. He is a member of BOINC@Poland.

The AP24 was returned on 6 Apr 2009 21:41:31 UTC. It was found by an Intel Xeon E5310 @ 1.60GHz running 32 bit Windows Server 2003 "R2". It took about 41 minutes 18 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 7960592659339799+2326495*23#*n for n=0..23. Credits are as follows:

Finder: Pawel Stachowiak
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the sections:


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP22

A new record AP22 (Arithmetic Progression of 22 primes) has been found. It is the AP22 with smallest known start 1322554958713, the previous record being 1365385579783 (2007, Jaroslaw Wroblewski). The finder is Jacek Kotnowski (sosnahojna) of Poland. He is a member of the BOINC@Poland team.

The AP22 was returned a while ago. Therefore, the WU has been purged and the details of time and computer specs are unknown.

The progression is written as 1322554958713+2861998*23#*n for n=0..21. Credits are as follows:

Finder: Jacek Kotnowski

New AP23

A new record AP23 (Arithmetic Progression of 23 primes) has been found. It is the AP23 with smallest known start 20389023122473, the previous record being 43760869165417 (2008, Raanan Chermoni & Jaroslaw Wroblewski). The finder is Eric Markle (Nikodemus) of the United States. He is a member of the BOINCstats team.

The AP23 was returned a while ago. Therefore, the WU has been purged and the details of time and computer specs are unknown.

The progression is written as 20389023122473+5785546*23#*n for n=0..22. Credits are as follows:

Finder: Eric Markle
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP23 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the sections:


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 60312982868878297 surpassing the old record of 25490711550130537 (2009, Andreas Kobara, PrimeGrid, AP26). The finder is Anonymous (AF>XTBA Pitheque) of France. He is a member of the L'Alliance Francophone team.

The AP24 was returned on 29 Jun 2009 15:41:58 UTC. It was found by an AMD Athlon64 X2 3800+ running 64 bit Windows 7. It took about 15 minutes 45 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 14992521666441877+8832442*23#*n for n=0..23. Credits are as follows:

Finder: Anonymous (AF>XTBA Pitheque)

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 60739320360456407 surpassing the old record of 60312982868878297 (2009, Anonymous, PrimeGrid, AP26). The finder is Carsten Hartwig (SG Arsenic) of the United Kingdom. He is a member of the SETI.Germany team.

The AP24 was returned on 3 Jul 2009 21:13:05 UTC. It was found by an Intel Core2 6400 @ 2.13GHz running 64 bit Linux. It took about 18 minutes 14 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 13432401425380607+9219580*23#*n for n=0..23. Credits are as follows:

Finder: Carsten Hartwig
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the sections:


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Carsten Hartwig (SG Arsenic) of the United Kingdom. He is a member of the SETI.Germany team.

The AP24 was returned on 17 Jul 2009 14:03:11 UTC. It was found by an Intel Pentium 4 @ 3.4 GHz running 64 bit Linux. It took about 34 minutes 37 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 19516186145019209+313705*23#*n for n=0..23. Credits are as follows:

Finder: Carsten Hartwig
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Tina Kent (Penguirl) of the United States. She is a member of Team MacNN.

The AP24 was returned on 20 Jul 2009 15:58:44 UTC. It was found by a Power Macintosh running OS X. It took about 71 minutes 33 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 20909681071069667+234797*23#*n for n=0..23. Credits are as follows:

Finder: Tina Kent
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found...the first by a PS3!!! The finder is Paolo Bassi ([FVG] bax) of Italy. He is a member of team BOINC.Italy.

The AP24 was returned on 3 Aug 2009 9:54:50 UTC. PS3's take about 7 minutes 30 secs to process an AP WU (each WU tests 3 progression differences).

The progression is written as 25545151920212759+1140241*23#*n for n=0..23. Credits are as follows:

Finder: Paolo Bassi
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 81531202836675089 surpassing the old record of 62869009767207037 (2009, Jan-Cornelius Molnar, PrimeGrid, AP26). The finder is Bryan Little (mfl0p) of the United States. He is a member of the [H]ard|OCP team.

The AP24 was returned on 23 Aug 2009 0:40:25 UTC. It was found by a PS3. It took about 5 minutes 30 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 13678065943093049+13223804*23#*n for n=0..23. Credits are as follows:

Finder: Bryan Little
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Martin Siegrist (sigi67) of Switzerland. He is a member of the SwissTeam.NET team.

The AP24 was returned on 15 Sep 2009 10:01:12 UTC. It was found by a PS3. It took about 5 minutes 30 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 1220728403569963+14348016*23#*n for n=0..23. Credits are as follows:

Finder: Martin Siegrist
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 83286253012572277 surpassing the old record of 82761689028005821 (2009, Kevin Erickson, PrimeGrid, AP26). The finder is John S Morris III (K7DMA) of the United States.

The AP24 was returned on 4 Oct 2009 21:12:31 UTC. It was found by an Intel 0000 (?) @ 2.40GHz running 64 bit Linux. It took about 13 minutes 44 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 3193781476385167+15609111*23#*n for n=0..23. Credits are as follows:

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Krzysztof Koczubik (ksysju) of Poland. He is a member of BOINC@Poland.

The AP24 was returned on 9 Oct 2009 10:46:58 UTC. It was found by an Intel Q9450 @ 2.66GHz running 64 bit Linux. It took about 7 minutes 35 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 18567190093510343+5352686*23#*n for n=0..23. Credits are as follows:

Finder: Krzysztof Koczubik

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 90769015637524109 surpassing the previous record of 84418532426419063 (2009, Anonymous, PrimeGrid, AP26). The finder is Ian Dickinson (Vato) of the United Kingdom. He is a member of Team-Goobee.org.

The AP24 was returned on 29 Oct 2009 17:41:04 UTC. It was found by an Intel Pentium III @ 1266MHz running 32 bit Linux. It took about 1 hour 20 minutes 28 seconds to process the WU (each WU tests 6 progression differences). A nice find for all the old timers (legacy systems) out there. :)

The progression is written as 3634080452156039+16981607*23#*n for n=0..23. Credits are as follows:

Finder: Ian Dickinson
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 104710589416588949 surpassing the previous record of 98090802848850701 (2009, Rosario, PrimeGrid, AP26). The finder is Roald Solbjørg (Roald) of Norway. He is a member of Team Norway.

The AP24 was returned on 12 Nov 2009 20:15:48 UTC. It was found by a PS3. It took about 11 minutes to process the WU (each WU tests 6 progression differences).

The progression is written as 4891686128805269+19453568*23#*n for n=0..23. Credits are as follows:

Finder: Roald Solbjørg
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP25

A new record AP25 (Arithmetic Progression of 25 primes) has been found. It is only the 5th known and now largest AP25. It has an ending term of 52115444782777781 surpassing the old record of 38271649410634609 (2009, Dale, PrimeGrid, AP26). The finder is Ian Dickinson (Vato) of the United Kingdom. He is a member of Team-Goobee.org.

The AP25 was returned on 24 Nov 2009 19:46:49 UTC. It was found by an Intel Pentium III @ 1266MHz running 32 bit Linux. It took about 1 hour 20 minutes 17 seconds to process the WU (each WU tests 6 progression differences).

The progression is written as 46176957093163301+1109121*23#*n for n=0..24. Credits are as follows:

Finder: Ian Dickinson
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds. Other improvements/builds provided by:

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the sections:


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is (James) of the United States.

The AP24 was returned on 1 Dec 2009 6:55:13 UTC. It was found by a Cell Broadband Engine. It took about 11 minutes to process the WU (each WU tests 6 progression differences).

The progression is written as 48306600448056229+1742643*23#*n for n=0..23. Credits are as follows:

Finder: Anonymous
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds. Other improvements/builds provided by:


  • Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
  • Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
  • Gerrit Slomma: Solaris build


The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP25

A new record AP25 (Arithmetic Progression of 25 primes) has been found. It is the largest known AP25 and only the 6th discovered. It has an ending term of 139751114244588403 surpassing the previous record of 52115444782777781 (2009, Dickinson, PrimeGrid, AP26). It is also the largest known AP24 with and ending term of 139751114244588403 surpassing the previous record of 108936498476106241 (2009, Zalewski, PrimeGrid, AP26). This is the first AP24 & AP25 found by the CUDA23 app.

The finder is Rune Nordbøe Skillingstad (runesk) of Norway. He is a member of Team Norway.

The AP25 was returned on 15 Dec 2009 17:30:00 UTC. It was found by an NVIDIA GeForce GTX 285 on an Intel i7 CPU 940 @ 2.93GHz running 32 bit Windows. It took about 9 minutes and 33 seconds to process the WU (each WU tests 9 progression differences).

The AP25 progression is written as 12353443596260323+23793841*23#*n for n=0..24. The AP24 progression is written as 12353443596260323+23793841*23#*n for n=1..24. Credits are as follows:

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Pawel Ferus (mindc) of Poland. He is a member of the BOINC@Poland team.

The AP24 was returned on 16 Dec 2009 13:46:09 UTC. It was found by an Intel Core2 Duo E7300 @ 2.66GHZ running Linux. It took about 47 minutes and 45 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 14698398021483853+24362735*23#*n for n=0..23. Credits are as follows:

Finder: Pawel Ferus
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 150127932982154623 surpassing the previous record of 139751114244588403 (2009, Skillingstad, PrimeGrid, AP26). The finder is Jesper Kågefors (wmjekag) of Sweden. He is a member of the BOINC Synergy team.

The AP24 was returned on 19 Dec 2009 10:41:13 UTC. It was found by an Intel Core2 Quad Q8200 @ 2.33GHz running Windows Vista 64 bit. It took about 35 minutes and 33 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 7448460750808573+27806605*23#*n for n=0..23. Credits are as follows:

Finder: Jesper Kågefors

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Jörg Steinmetz ([SG]marodeur6) of Germany. He is a member of the SETI.Germany team.

The AP24 was returned on 20 Dec 2009 10:11:58 UTC. It was found by an Intel Core2 Quad CPU Q9450 @ 2.66GHz running Linux. It took about 25 minutes and 55 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 44265615051136733+7821972*23#*n for n=0..23. Credits are as follows:

Finder: Jörg Steinmetz
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

The AP24 was returned on 21 Dec 2009 21:41:42 UTC. It was found by an Intel i7 920 @ 2.67GHz running 64 bit Linux. It took about 33 minutes 22 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 29051233904541803+18765591*23#*n for n=0..23. Credits are as follows:

Finder: Krzysztof Koczubik
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. It is only the 8th known AP25. The finder is David Chevalier ([AF>XTBA>XTC] Markken) of France. He is a member of the L'Alliance Francophone team.

The AP25 was returned on 25 Dec 2009 11:43:32 UTC. It is the first found by a PS3. It took about 17 minutes to process the WU (each WU tests 9 progression differences).

The AP25 progression is written as 29952203513013839+8769895*23#*n for n=0..24. Credits are as follows:

Finder: David Chevalier
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Robert Scullin (Robert Scullin) of the United States.

The AP24 was returned on 28 Dec 2009 9:04:47 UTC. It was found by an NVIDIA GeForce GTX 275 on an Intel Core2 Quad Q6600 @ 2.40GHz running 64 bit Windows 7. It took about 14 minutes and 16 seconds to process the WU (each WU tests 9 progression differences).

The AP24 progression is written as 63445575002484173+2307769*23#*n for n=0..23. Credits are as follows:

Finder: Robert Scullin
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is 郭俊毅 (diz_Child) of China. He is a member of Team China.

The AP24 was returned on 2 Jan 2010 6:05:26 UTC. It was found by an Intel Pentium Dual T2330 @ 1.60GHz running 32 bit Windows XP Professional. It took about 1 hour 21 minutes and 26 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 47951620104244397+11867770*23#*n for n=0..23. Credits are as follows:

Finder: 郭俊毅 (Junyi Guo)
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

The AP24 was returned on 5 Jan 2010 19:33:24 UTC. It was found by an Intel Xeon CPU E5440 @ 2.83GHz running Linux. It took about 25 minutes and 7 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 36629598861376343+11370937*23#*n for n=0..23. Credits are as follows:

Finder: Edward Gordon
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Donald Hatland (Don Hatland) of the United States. He is a member of team USA.

The AP24 was returned on 15 Jan 2010 8:30:37 UTC. It was found by an NVIDIA GeForce 8800 GT on an AMD Athlon 64 X2 4200+ running 64 bit Windows 7. It took about 22 minutes and 51 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 29578980078344351+23462565*23#*n for n=0..23. Credits are as follows:

Finder: Donald Hatland
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Bryan Little (mfl0p) of the United States. He is a member of the [H]ard|OCP team.

The AP24 was returned on 28 Jan 2010 9:05:09 UTC. It was found by an Intel Core2 Quad @ 2.40GHz running Linux. It took about 31 minutes and 12 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 77964779011754827+1320946*23#*n for n=0..23. Credits are as follows:

Finder: Bryan Little
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Jon Sonntag (Slicker @ SETI.USA) of the United States. He is a member of the SETI.USA team.

The AP24 was returned on 2 Feb 2010 23:48:04 UTC. It was found by an Intel Core2 Quad @ 2.40GHz running 64 bit Windows Vista. It took about 33 minutes and 20 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 36216875966560057+24123429*23#*n for n=0..23. Credits are as follows:

Finder: Jon Sonntag
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Paweł Kaczmarczyk ([B@P]filavandrel) of Poland. He is a member of the BOINC@Poland team.

The AP24 was returned on 23 Feb 2010 8:31:09 UTC. It was found by an Intel Core i7 920 @ 2.67GHz running 64 bit Windows 7. It took about 43 minutes and 54 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 28177336417360261+25675304*23#*n for n=0..23. Credits are as follows:

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is Uros Vizintin (Uros Vizintin) of Slovenia.

The AP24 was returned on 2 Mar 2010 12:11:46 UTC. It was found by an NVIDIA GeForce 8600 GT in an AMD Athlon 64 X2 6000+ running 32 bit Microsoft Windows XP. It took about 40 minutes and 48 seconds to process the WU (each WU tests 9 progression differences).

The progression is written as 31884137812843999+26514806*23#*n for n=0..23. Credits are as follows:

Finder: Uros Vizintin
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App
Iain Bethune & Bryan Little: Mac CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

New AP25

A new record AP25 (Arithmetic Progression of 25 primes) has been found. It is the 14th known AP25. It has an ending term of 178450656331295477 surpassing the previous record of 144822829106549969 (2010, Pattenden, PrimeGrid, AP26). The finder is Dave Sunderland (DaveSun) of the United States.

The AP25 was returned on 13 Mar 2010 9:38:26 UTC. It was found by an Intel Pentium 4 3.20GHz running 32 bit Windows XP Professional. It took 2 hours 5 minutes and 18 seconds to process the WU (each WU tests 9 progression differences).

The AP25 progression is written as 25300381597038677+28603610*23#*n for n=0..24. Credits are as follows:

Finder: Dave Sunderland

New AP24

A new AP24 (Arithmetic Progression of 24 primes) has been found. The finder is (sbbr) of Estonia.

The AP24 was returned on 18 Mar 2010 9:07:00 UTC. It was found by a Cell Blade Server with two Cell/BE processors (16 SPEs). For Cell/BE processing, it takes 1 SPE about 81 minutes to process a WU (each WU tests 9 progression differences).

The progression is written as 69067110822206929+6753086*23#*n for n=0..23. Credits are as follows:

Finder: Anonymous
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App
Iain Bethune & Bryan Little: Mac CUDA23 App

The AP24 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP26. :)

AP26 Found!!!

The first ever AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Benoãt Perichon ([AF>HFR>RR] Jim PROFIT) of France. He is a member of the L'Alliance Francophone team.

The AP26 was returned on 12 Apr 2010 20:03:44 UTC. It was found by a PS3 running Linux. For Cell/BE processing, it takes 1 SPE about 81 minutes to process a WU (each WU tests 9 progression differences). The PS3 can do 6 WU's in parallel.

The AP26 progression is written as 43142746595714191+23681770*23#*n for n=0..25. Credits are as follows:

Finder: Benoãt Perichon
Project: PrimeGrid
Program: AP26

AP26 was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.

Bryan Little: PS3/Cell Blade App: "AP26 port to Cell/B.E. Linux platform"
Bryan Little: Linux,Windows Apps: "Vectorized cpu-intensive scalar code and built applications with Intel(R) optimizing compiler"
Gerrit Slomma: Solaris build
Gerrit Slomma & Bryan Little: CUDA23 App
Iain Bethune & Bryan Little: Mac CUDA23 App

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


It has been a most challenging and rewarding project. It was also PrimeGrid's most versatile project when it came to offering applications to the most platforms. Congratulations to everyone who has participated in this search.
