The next step would be to find the status from Christophe Clavier and associates ([url]http://mersenneforum.org/showthread.php?t=11625[/url]). For one reason or another, he keeps his webpages out of sync with the most current state and he doesn't update them in factordb; you can only find the state by contacting him.

ECM at B1=3e6 cut off an easy p26, leaving a C129.
EDIT: and the same ECM run ended up factoring the C129 as p37 * p93.
EDIT2: at index 5156, the C168 is p29 * p139.

Quite some time ago, someone (maybe Mini-geek or schickel, or maybe it was you) got a current set from Christophe and I helped update factordb from that set. Perhaps it is time to try again?

It would be much faster to GNFS that c130 now, though.

I have several hundred @ 11e6 & 43e6 so we are well past the ECM cut-off.
Here is good poly if you want to feed it to factMsieve. Don't forget to sieve on the -a side.

I fired up gnfs, but I may not be available at the necessary time(s) to get the factors posted promptly.

Thanks for the poly...

Bummer! I estimated 16M relations needed, but 17M failed, so I'll be a bit later in my factors since it will be a while before I get back to the computers...

Edit: 18M has succeeded - later...
