Finished B1=1e6, 948 curves (on three cores) for the c137, so t35 level. Here I stopped.

BTW: the most recent loss of the 3 is just about higher than the old one at line 2471, so it is a new record for the highest sequence to become stable.

ECM anyone?

I have done ~150@11e6 so far and queued some more, but with my smallish ressources (compared to others here) it will take several days to finish something like 5000@11e6...

lots of progress

i will join you with ecm
starting some curves at 43e6
