There are 13 sequences shown on the list with a cofactor size of <= 116. Their C-sizes are 86, 102, 106, 110 (8 of them), 114, and 116.

I have cleared them.

If I've observed/calculated correctly, all sequences are now C>=123 and we've now dropped under 400 remaining.

There are now 373 sequences shown.

I hope to have a second list by cofactor size in a little while. I've been leaving a few of the smallest ones for others to complete, including yourself.

I have run ECM t40 up through 63^97 and am expecting to continue with that work from 63^98 today.

I still need to do some script edits, so will be working probably above c135 in a little while with NFS.

I factored the 5 sequences that were C<116. I've queued up the next 4 that are C<126.

I ran a full set of curves (31% of factor size) on all C<=131.

I got 3 splits. 58^97, 77^94, and 87^78.

58^97 was lucky with a P45. 77^94 was ridiculously lucky with a P50!

So there are now 18 sequences at C<=131 that are ready for NFS.

Good hits!

Are you going to run the C≤131s. I've been leaving the smaller ones for you.

Funny you mention that. In the last hour, I got a couple of faster terminations, one that freed up my Ryzen. I want to run some more ECM here since that machine is far faster than anything else I have at specifically that task. Another machine handled the C<=131s but above that, it would have to go past t40. It gets pretty slow at that point.

I'm going to load everything up to C133 for full ECM and see how long it takes. I'm aware that you've ECM'd everything <= base 77 to t40 and that everything else is at least at t35. If it's taking too long, I'll stop it at some point.

After that, I'll start running some NFS here.

All sequences for C<=133 have now been fully ECM'd.

There were 2 more splits in the C132-133 range: 48^93 and 92^91.

I'll take the remaining 11 sequences at C<130 for testing.

I forgot to post last night that I'd run t40 through 86^96. I'm continuing upward from that point today. I'll look for any c<134 and pull them from my list.

We're trimmed the original list by well more than 50%!

All sequences with cofactor C<130 digits have been cleared.

Next I will do full ECM on all C134-135.

All sequences for C<140 have now been fully ECM'd.

There was only one split for C134-135. Many of them were already at t40 so didn't have much more to do.

I'll take the C130s and C131s for testing. Total of 7 sequences.
