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:

New AP25

A new record AP25 (Arithmetic Progression of 25 primes) has been found. It is only the 2nd known and now largest AP25. It has an ending term of 15523154536267043 surpassing the old record of 8132758706802551. It is also the AP25 with smallest known start 2960886048458003, the previous record being 6171054912832631. The finder is BOINC@Poland's "Super Computer" (SKB@P). It is a farm of machines funded by BOINC@Poland members.

The AP25 was returned on 8 Apr 2009 14:37:49 UTC. It was found by an Intel C2Q Q9450 @ 2.66GHz running 64 bit Windows XP Professional. It took about 12 minutes 20 seconds to process the WU (each WU tests 3 progression differences).

The progression is written as 2960886048458003+2346233*23#*n for n=0..24. Credits are as follows:

Finder: BOINC@Poland
Project: PrimeGrid
Program: AP26

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

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 Bryan Little (mfl0p) of the United States. He is a member of the [H]ard|OCP team.

The AP24 was returned on 11 Jul 2009 14:54:08 UTC. It was found by an Intel Core2 Quad @ 2.40GHz running 64 bit Linux. It took about 15 minutes to process the WU (each WU tests 3 progression differences).

The progression is written as 7979661543967237+9936237*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 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 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:

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 record AP24 (Arithmetic Progression of 24 primes) has been found. It is the largest known AP24. It has an ending term of 162591685359957911 surpassing the previous record of 150127932982154623 (2009, Kågefors, PrimeGrid, AP26). The finder is Dave Mumper (Mumps) of the United States. He is a member of the SETI.USA team.

The AP24 was returned on 21 Dec 2009 2:36:06 UTC. It was found by an Intel Xeon CPU 3.40GHz running Linux. It took about 1 hour and 7 minutes to process the WU (each WU tests 9 progression differences).

The progression is written as 6450318626856161+30430175*23#*n for n=0..23. Credits are as follows:
