I can do GNFS on the C153 if it has received enough ECM.

I am doing it, it will finish quite soon, so it's not necessary that yoyo@home does it.

I have added some more term to the sequence (and currently doing ECM on a C194).

I've ECMed the C194 with 14716 curves at B1=110M (yafu's default for t=55), without luck. I'm stopping working on it.

Nice hit!

Unfortunately, the D2 is difficult to lose, especially at this size. On the bright side, if it does not get a 3, then it is steady (i.e. it doesn't grow much), and 5 is not sticky. But unless we double the seven, there is no much hope...



Maybe we could find a "better" sequence to tickle? :wonder:

It's now a C167. I've ECMed it with 7553 curves at B1=43M without luck and I'm dropping it.
