After this run, this c166 will be GNFS ready.

3000 at 110e6 is roughly equivalent to 7500 @ 43e6; after the 2500 already done, we are already past t50.

If you do any more curves, they should be at 110e6 or higher.

No factor.

A poly is requested [URL="http://mersenneforum.org/showpost.php?p=370734&postcount=420"]here[/URL] for index 1399.

C163 @ i1401
 

2 * 3 * ... * C163

-pm1 5e9 - no factor.

P.S. Thanks to [B]ryanp[/B] for running the GNFS job on the previous C166.

Now it's a C171 @i1488. It has endured up to t45 with no factors found.

Is someone still working on this? It has moved on quite a bit since the last post.

C176 @ i1585
 

It appears this sequence has not moved since July 23, 2014.
No ECM has been reported at this index.
I would say it is dormant.

Currently at 2 * 3^3 * 5 * ... * C176.

Unstickying. If anyone wants to work on it and wants it stickying again just shout.

A C176 seems like a nice forum target after M991 is complete. If someone gets ECM started, I'll contribute some curves. Has even a t45 been done yet?
