Files from n=870 are now on the server.

We are continuing with only 12 Ks, since k=51 and k=57 were already tested from 870k in a "backstage" effort after Benson reported his primes. This gives us a reduction in number of candidates per 1000 n's of about 1/8th (720 --> 630).

Please join us to find your next large prime (with more than 260,000 digits) and to help us complete the 5th RPS Drive!

I meant n's - sorry.

You should not expect Carlos to reply to your message- he has sworn off this forum, and an email discussion I had with him indicated he will not return in the near future. Doesn't really matter, since Amphoria is going to complete that file.

We have no idea what candidates (n's) Carlos tested because he decided to leave without reporting his status. That is unusual and uncommon behaviour but it's his business. We are continuing without him. When you have available resources please reserve the next available range (872-873 as of this writing).

Thanks, and I wish you to hit your next prime soon!

Thanks to amphoria for filling the 843-844 gap!

The tests for all 14 Ks are now continuously completed to n=864000 and the k=51 and k=57 gaps caused by Benson searching ahead of us are now closed.
