17030 curves done so far without factor. I run up to 18000 curves.
What is needed next?

2t50 was probably enough, so your curves are more than sufficient. We'll do poly select soon and get it fed to the 14e queue.

I can do the linear algebra if you need it.

The c167 is factored and reported to factordb. I did zero ECM on the new line.
Go, Ricky, go!

The latest composite is a C154 (ECMed to t25) after three easy lines.
Edit: C126 at t30.

The C126 factors very nicely as p63*p63!

It's now a C196... I've ECMed it to t=50. I think yoyo@home may be interested to go to t=55 at least... or perhaps even to t=60.

Anybody still working on this? Has yoyo been contacted about ECM?

Default C196 @ i12534

I see yoyo has completed t55 + 20K @ 26e7 and is nearing 12K @ 85e7. That should be plenty to start GNFS poly selection.

about 600 thread-hours on CADO poly select yielded this:

I don't recall a good way to run this through msieve to find the usual score; if someone could do so we can compare it to the C196 record and decide how much msieve-GPU poly select to continue with.
