Well, there we go.

Beware! Downdriver hunters in sight! :smile:

(not me! I have no contribution to this sequence up to now, but I was thinking to reserve it when it will reach 83 digits and get some 2^3*3*5 driver, and the people/poachers will lose the interest... to grab it for myself and bring it back to 150 digits :smile:)

(edit: hopefully by then I could free 3-4 cores...:whistle:)

Wrong direction. Better lose a 2 and stay at 3^0... :wink:

So, has the C114 been fully ECMd, or did whoever was running the sequence give up on it?

akruppa 2012-05-09 13:38

Looks like everyone was just hoping for an ECM factor. I start NFS.

Actually, I just came back from a meeting to notice that by accident I had left the computer running ECM on the number (I was hoping to get a lucky hit with a few curves). I ran 3k@3e6 + 1k@11e6... so yes, it should be ready for NFS.

akruppa 2012-05-09 19:23

Done. This was the first NFS factorization I've done in weeks that didn't get pre-empted by someone else. :smile:

Edit: 2^4? :huh:

Edit: did p40 on i3301 c123. Edit: And another 2400@11M.

LaurV 2012-05-10 02:55

C123=3 (mod 4)
C123=2 (mod 3)
C123=4 (mod 7)
C123=19 (mod 31)

:smile:

jrk 2012-05-10 03:15

I did 2400 curves @ B1=4e6, B2=11415205630 on line 3301 c123. NF

Starting NFS. But feel free to beat me if you can.

But looks like someone did beat me afterall. :smile:

akruppa 2012-05-10 16:00

i3307 c118 now. I did 300@3M so far. Others probably did a lot at 3M as well so I switch to 11M for now. Is anyone doing NFS already? If not I can take a shot at it.
