There is a C133 now at line 2797... I think I'll let our mystery helper continue with it for now. Although the childish part of me wants to throw 200 cores at it and be done within the hour, just so that he/she can be dissapointed for once...

Man, did we just dodge a bullet!

Line 2795 was this:[code]2795 c155 = 2 * 26540231597764915875748523921286155358287735668816451607271020126944017648528345710110955950716807274798345163208946240501455091962907345828078337693949271[/code] [SIZE="1"](Or c155 = 2 * p155)![/SIZE]

This mystery worker has quite a lot of cores - they're doing c13xs in about a day. Ben, can you throw loads of cores at the c149? It would be nice to get it out of the way quickly anyway.

I can put 48 cores on it, but I can't start until tonight after work (10 hrs from now). I'll start 6 cores on ecm until then.

Found 197765000678978787299763869154327257712005970001

Edit: did p40 on the c136, continuing at 11M. Did about 2500@11M, moving on to 44M until someone starts sieving. Edit: Started poly search. Edit: Sieving. Edit: Linear Algebra.

Done. Now a c132 at step 2804. I'm currently running curves at 3M.
