Who has plans for the line 2943 c156? I am running polynomial selection at the moment and plan on doing so for a few more days.

Batalov 2012-03-21 03:31

If RSALS would sieve, I could do algebra (or will gladly let someone else).

Gimarel 2012-03-21 04:54

3200@43e6 on the c156

RSALS can sieve :smile:

Thanks. Here's a poly:

I trial-sieved four polys with score from 2.728e-12 to 2.801e-12.

Has the number survived enough ECM work ? :smile:

Batalov 2012-03-25 08:34

Did anyone accidentally throw 17800 11e7 curves at the c156? Don't be shy! ;-)

yoyo 2012-03-25 09:08

I'll run them.

t55 on a poor little C156 ? :surprised

I queued "C156_4788_2943" to RSALS today.

No but I ran 500 curves @ B1=8e7, B2=9.7e11
