If anyone has the time I could use help on a poly for the C182 from 2005020:I15163
Code:
1486514753904429942695224504469584079595950333208375118736195131198955787658638937354019735933501170888427595518315288217393322486325601233455956498507105789205640526849636735166249314865147539044299426952245044695840795959503332083751187361951311989557876586389373540197359335011708884275955183152882173933224863256012334559564985071057892056405268496367351662493

I am running a CPU poly search on this number for coefficients up to 1,500 using msieve through YAFU, and my intention is to use NFS@Home for sieving once a suitable poly is found.

Thanks very much!

Rich

I have only this

hmm you have not the right number.

Default C175 poly

Thank you very much, charybdis and firejuggler for your polys. My cpu searching is still underway but I will advise how that came out.

My 300 thread-hour cpu search came up with only a 1.36e-013 so I'll be testing your polys.

Thanks for the quick work! That would of taken me a week (or longer). I have to move computers around in my home office over the weekend and will start sieving sometime Monday.

I'm looking for a poly for C183 from aliquot sequence 933436:i12561. Here is my best poly, also I've attached top-15 polys with highest e-score.

How about an early spin with over 13.5% better in the E score?
Sorry for the increase in the skew, I'll see what can be done.
Code:
Y0: -234010363290294797535840494515081019

skew: 102591382.05
# size 6.515e-18, alpha -8.569, combined = 5.459e-14 rroots = 3
The spun poly comes from a very lucky/rare spin (c5' = 2 * c5, Y1' = 2 * Y1) of
Code:
# norm 6.247592e-18 alpha -8.568180 e 4.652e-14 rroots 3

It was #10 in the top 15 list in the attached c183.polys.txt.
Thank you, unconnected, for sharing!
And still too low to compete with the current (August 2020) C183 record of charybdis (6.382e-14).
Will re-run through CADO, it might get better.
Happy test-sieving so far!

skew 1367091201.68, size 6.377e-018, alpha -8.529, combined = 5.338e-014 rroots = 5
Thats an early find and the skew is horrible.
