David, could you send me the n=2500-30K sieve file you used for this range? I'll need it to process the PRPnet-formatted results and verify that everything's there.

here it is
i undersieved as i thought i would remove several ks early on and speed up the sieving
this plan failed as i didnt get the flurry of primes i expected early on

David, I need primes n<2500. Can you post those please? With only 4 primes n>2500, I can't show a top 10 on the pages without those.

Max, it would be a lot cleaner to get all of the results in one batch instead of separated by primed and unprimed k's. I try to keep everything somewhat consistent in my file storage. Also, on the primes. I just need only those...the primes. No "is prime" or "time: 0.0" on each line. Doing those two things would make it consistent with a pure PFGW run.


Thanks,
Gary
