double-check for 8 k's 213<=k<=291 complete

Kosmaj,

The double-check effort that you requested for k=213, 237, 249, 261, 267, 273, 279, & 291 has completed. No problems were found.

Ranges will be reported to Wilfred Keller.

Good questions. I can't speak for Kosmaj but I don't think he'd have a problem. I think his objection would come in more if it were k < 300 and/or if we ended up getting reportable primes out of it....

Thanks, Carlos. That would be great. I'll let you know. I'm shooting to start the effort in March-April 2008 after my 12 heavy-weight k's are done LLRing to n=400K. (Very rought estimate.)

300<k<=1001 for n=50K-100K double-check complete

I have completed all k-ranges for the double-check for 300<k<=1001 for n=50K-100K. The ranges left to report were for k's in the 600s, 700s, and 800s. This was the most problematic area. I have found...

Now checking k=301-1001 for n=50K-100K

After getting a sieve file from Anon (thanks Anon!), I have started doing some LLRing for a double-check of the range 300 < k <= 1001 for 50K < n <= 100K.

This is a large LLR effort and I will...

Kosmaj,

It looks like Prof. Keller's ranges page for Riesels has been updated to include the ranges that I double-checked.

In looking at his page, I see that there are many ranges that have...
