I see a C88! (Not taking it, though.)

I'm taking it

Now I am NFSing the c96.

It's starting to get ugly!
Keep your fingers crossed! At an awe-inspiring height, we're looking at c154 = 2[sup]7[/sup] * 3[sup]2[/sup] with a c[sub]140[/sub] GNFS job possibly in the future. And it's still in high gear! (In fact with the exponent creeping up one, it's added a little bit of speed.)

We need to catch a lucky break soon!

Actually, it is 2^7*3^2*17. The good news is that, because of the 17, the 3^2 will stick around. So, with a favourable split, you can drop the 2^7. Bad news is, it ain't gonna be on this iteration.

ECM efforts are currently around t40; we need to do a few 11e6 curves, maybe 1/3 of t45, before doing a GNFS.

jrk 2009-05-19 06:28

I did 2000 curves @ 3e6.

So now well past t40. Team sieve?

Sure. I'll be glad to do the postprocessing (plus FTP hosting--same as before, this time in directory c140-relations) again if nobody else is particular itching to do it.

Any volunteers for a polynomial search?

jrk 2009-05-19 06:34

msieve wants 58 hours for a poly search, so we may want to split it into parts.

All times are UTC. The time now is 12:03.
