1423*22178363- 1 is prime (655,756 digits)
1423*22179023- 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
Code:
1 GIMPS        14    56.3333
2 PrimeGrid  3708.5  53.3705
3 RPS         616.5  51.3939
4 SOB           7    51.3934

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)
