This is my largest prime and 2nd largest CRUS prime

Congrats Dmitry! I cannot believe how fast the k's are dropping on this base. This is worthy of a few dancing George's: Only 3 k's to go! Last fiddled with by gd_barnes on 2010-06-23 at 10:11 |

 I must admit, I'm rather surprised this one came as soon as it did, continuing what would seem to be an extremely "lucky" streak. Hopefully the rest will fall similarly!

I have posted an updated sieve file with k=77743 removed. There are now only 3 k's remaining and only 2 k's remaining to be searched for n=600K-1M.
Because we have found so many primes and k=77743 was the highest weight k of the 4 that were previously remaining, no more sieving will be needed up to n=1M. Also, there are now only 3058 candidates remaining to be tested up to n=750K. So...let's put a push on to move this drive towards n=750K over the next few months. If the interest is still here once we push past n=750K, I'll start a sieving drive for n=1M-2M for the remaining 3 k's. We can then discuss if we want to continue the team drive or if people would like to reserve individual k's for testing. |

Thanks all for congratulations! I do my best and here is another probable prime.
43994*6^569498-1 is a probable prime! Wd1: 4BF6C3BE,00000000 Need to check with pfgw. I'm very lucky with Riesel base 6, so I take remaining k=36772 to 750k. Last fiddled with by unconnected on 2010-06-28 at 10:16 |
