update on k=93
k=93 has been sieved until 440bn for 330000<n<400000 and 3600 tests are left.
I hope (expect!  ) that I will find at least 1 prime in this range, for I am searching a long long time on a new one.

I'll take k=191 a little bit further. The stats page reports that it is tested upto n=270000, so I'll start there. Please let me know, if someone else is already testing this k.

Thomas, thanks for your report, I updated the stats page, and reserved k=191 for you. I'm not aware that anybody else is working on it.
BTW, I cancelled outstandig reservations by Jeffrey of k=9, 51, 59, and 117. It's possible that he checked these k's to a little bit higher limits than indicated but I have no means to find out. I think he stopped all his clients shortly after he found a prime for k=9 at n=828k. |
