i have had 2 more primes since n=3k
744*589^4026+1 654*589^5638+1 i am now tested upto n=20k this lack of recent primes is getting frustrating

I don't blame you for being annoyed. If there's one thing I've personally found with the very large bases, it's that you can go into extremely long stretches of no primes after a large grouping of primes. I'm sure Ian can relate the same experience.

this was based on data after the primes just mentioned i found the prime for 5k10 before the analysis but am still owed the prime for 10k20k i suppose i was being lucky before cant wait for finding another prime

Riesel base 707 proven with prime:
12*707^105721 No, I did not reserve it. I just took a bunch of bases that had a few k left where n < 25000 and are taking them to n = 25000 as part of my testing for the upcoming PRPNet release. I will avoid stepping on toes by not posting primes for bases reserved by others. Last fiddled with by rogue on 20091231 at 14:38

Riesel base 1019:
the only k=2 is at n=91k (so about n=910k for base 2) no prime yet. continuing.
