Got it. Sorry for the oversight. And thanks for the poly.

I'll wait until I've factored those 3 before I submit any more numbers (unless you are running out of test cases).

If this offer still stands, would you mind attempting to find a good poly for this C169?

Code:
2203286292154236920662074580008136560385550762038571072069284129582298550469011615783387269827436918721335468107066200517568432204890391543672088684775850203864157356993
It's a cofactor of C169_123_109 from the xyyx project.

I can reciprocate by running some ECM or other factoring task for you.

Thanks.

 2013-07-16, 03:34 #50 VBCurtis     "Curtis" Feb 2005 Riverside, CA 13·421 Posts I'll give the C169 an overnight run too, and then run the c176 while away on another trip wed-sun. No improvement in day 2 of C176 from the 1.32e-13 I had in day 1.

 2013-07-16, 04:15 #52 wombatman I moo ablest echo power!     May 2013 22×11×41 Posts Polynomial Request Thread Far be it for me in all my newbie-ness to proclaim anything, but given the recent spate of number requests, I thought it might be nice to have a thread devoted to requests for polynomial searches by those of us with free GPUs so the numbers aren't lost in the jumble of a thread. I don't know who moderates this particular forum (Jason?), but it'd be nice to be able to edit this post past the typical 60 minute limit, if possible. In case the board isn't able to do that without a lot of effort, I'm going to make a google document to store all the requests, those who have announced intentions to search (and what intervals, if that is specified), and perhaps the best poly score provided for a given number. In terms of general ground rules, my thoughts are that they should be something like this: 1) Unless otherwise specified by the person requesting, any number of people may choose to search on a given number. 2) If the factoring of said number leads to any kind of publication or something similar, the person who found the polynomial used must receive appropriate recognition (listed as an author on an article? I would welcome suggestions here). Honestly, I think that covers the best stuff--if anybody has any other suggestions, please feel free to comment, and I'll add them. For now, the google doc is located here: https://docs.google.com/spreadsheet/...0E&usp=sharing I think it will not be accessible until your email is added. Worse comes to worst, I can email it to you. If you would like to be added, just PM me your address. I do solemnly swear your email will only be used for good!
