Now, a c161 in i5193. It had survived 10k 260e6 curves (>t55). Ready for GNFS by the forum.

The next line has a c164 that has, so far, survived t30 and 220/904 curves of ECM with B1=1M

It survived t40 (2350 curves@B1=3M)as well. Needs more ECM (t48 or so?), but I've stopped on it.

I'll start a few thousands @ 11e6.

4500 @ 11e6 - nothing.
8e9 -pm1 - nothing.

I'll start a run of 43e6 overnight.

Passing thru

Started another short run, passing thru
80 @ 11e7

5000 @ 43e6 - nothing

Final push.
100 @ 26e7 - nothing.

Should I give it a try in yoyo@home?
How many curves on which B1?

A c164 need about 16500 curves at 11e7 (nearly a t55, by the 1/3 rule).
RichD has done 1000 curves, and 500 curves by me, so there are 15000 curves left.
