[QUOTE=jyb;511102]Can someone explain the purpose of that thread? What prevents one from just creating a Pastebin post oneself?[/QUOTE]

Viruses, malware, etc. I got stung twice before deciding it was better to avoid sticking my hand in the hive. Maybe it has gotten better but I won’t go there. YMMV.

I will take a look at it tonight. Releasing your reservation.

Taking 4784213763211_17m1.

It is an octic. A patch was added to Msieve a couple years ago to handle higher degree polynomials. Perhaps [B]richs[/B] has a version before that was applied.

My version is v1.53 from 3 or 4 years ago. I see in the Msieve thread there are newer SVNs so I'll update. Rich, thanks for the heads up!

It will be a day before I can get to it. If you happen to get it working today, feel free to run with it. Just let me know. I will start on it first thing tomorrow (Sat.) morning.
