B2 over at Riesel Sieve has a theory that "primes come in bunches"--and it seems to be somewhat correct, at least for the 5th Drive! :smile: Also for k=58695, it seems.

If you include the prime found by Benson for k=51, this file contains 3 primes so far.

Congrats to amhoria and Carlos on a nice series of 800k and 900k primes! We are doing great these days, approaching 500 primes by number, as we just reached 47.5 by score. :cool:

Only one more to go for RPS to have reached 500 primes! :banana::banana::banana:

201 799611 is prime.
Sadly, this was the 498th prime, earlier Wednesday.
201 had been reported complete to 840k- I failed to check the primes file after noting the search file complete to 800k and starting a new search range.

Cruelty, a nice and important prime because k=281 was the only k<300 with no primes with more than 100k bits!

Next target: 200k bits, there are 4 Ks with no primes larger than 200k bits: k=109, 221, 233, and 283. All reserved by you !! The one with the minmax prime is k=221: n=104846.

Congrats. I think that's the largest RPS-prime since I joined.

Edit: By the way.. it is strange that I have an avatar now. I have added none, but it looks nice anyway.
