 I pulled a status on the sequences in the top posts and culled the ones that were not 2^2 * 3 (and not reserved)
Thanks: good work!

I hereby release the sequence, ECM to t30 of current line.

*sigh* It was great while it lasted.

Bummer.....that was such a nice plateau going there at the end.

Sounds good. If it gets too far out of hand, maybe we could make this a second community project.

It's not as if anyone is working on the first project

Yeah, unfortunately, things become a lot less interesting when there's a driver involved.

I'm currently working on a c146 right now. Maybe I'll tackle the c134 when that finishes, if no one else has by then.

You were soooooooooo close!
As I said thousands of times... never give up as long as you still can do it...
The C138 splits after about 3.5 hours of ECM with yafu on 8 cores, custom plane, pretest ratio 0.33 (curve 2048 of 3920 at 11M, I usually do a third of length of ECM for this size).
Code:
PRP45 = 725834229594254558107589572868779796520446527
PRP93 = 451967850884333874529293559315343323505211497431830241192406827521397051002074114357729804389
Next term was easy split. Still going on with the sequence (now a C141 seems a bit harder).

Yes, there is a P20 or P21 which I will report to FDB in few minutes, let me look in the logs for it, it was found by ECM in the very beginning (few minutes). The C141 is almost at the end of 11M range (almost 4000 of 4480). I will finish this C141 because there is a 3^4 and it has a small chance to lose one 2.
After this you can have it back regardless of the result, if you still want it.
