The first work for 32+1 has been inserted. Here are some details:


  • sieved to p=600T; ongoing
  • 206556 total candidates
  • 28834 candidates up to n=700K soon to be completed in LLRNet
  • 177722 candidates remaining for BOINC; however, we continue to sieve so this will decrease
  • first work inserted 700K<n<1.5M (33175 candidates)
  • ~41K candidates per 1M range of n
  • status can be monitored here: 321 Range Statistics


Known primes in our workfile are at n=709968, 801978, 916773, 1832496, 2145353, 2478785. We hope to find at least 2-3 new primes below n=5M with one being a Mega Prime!

Good Luck and thank you for participating! :)

And here you have some FFT jump that increase time to crunch them.

Known primes in our workfile are at n=709968, 801978, 916773, 1832496, 2145353, 2478785. We hope to find at least 2-3 new primes below n=5M with one being a Mega Prime!

Today the last WU with n<5M was finished and only one new prime was found (n=2291610), no Mega Prime. :|

Let's hope that we have more luck now at n>5M. At least the next prime will definitely be a Mega Prime. ;)
