And now RPS is 3rd by score, only 5E-4 ahead of SOB, so we'll postpone the "party" until we have a more comforable lead Code: 1 GIMPS 14 56.3333 2 PrimeGrid 3708.5 53.3705 3 RPS 616.5 51.3939 4 SOB 7 51.3934 Last fiddled with by Kosmaj on 2015-10-24 at 01:22

Thanks, Kosmaj!

It's been a very dry period since my last primes found in April this year.

BTW.: What about that "party" you announced two weeks ago? Our lead is now close to 1E-2 and thus quite comfortable now...

I haven't found any large primes in quite a while, but here's one to widen our lead:

39*2^2251104-1 is prime! (677652 digits)
