1423*2[SUP]2178363[/SUP]- 1 is prime (655,756 digits)
1423*2[SUP]2179023[/SUP]- 1 is prime (655,955 digits)

Very interesting small gap between the 2 primes with n so large. k=1423 also has a very low nash weight of 309.

Hi Trilo,
Great primes!
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 :smile:

Hi Thomas,

Congrats on nice primes!

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... :wink:

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)
