Thanks for trying Max.

Taking all c5 < 2M.

I'm done. Will see if Max can spin it, after which I'll test sieve this the top polys and submit the job.

C185 polys
 
The last two polys don't spin up, sorry. And 4.159e-14 is a new record.

Hi Max, are you able to spin up this poly for the C162 from Aliquot sequence 434040, i3099? This poly resulted from 300 CPU hours of searching.

poly for C157 kindly request
 
Would anyone be willing to do poly search on that one [FONT=Calibri][URL="http://factordb.com/index.php?id=1100000001431822570"][COLOR=#0000ff]C157[/COLOR][/URL][/FONT]- possibly good as e = 2.5e-12 ?
With simple yafu (no CADO nor Msieve) I do not receive reasonable polys.
Thanks a lot in advance,
cubaq

PS. Please use format of nfs.dat.p I.E.

C157 poly
 
Actually that is not too bad. Msieve says to expect poly E from 2.42e-12 to 2.78e-12. I'll throw a couple hours of gpu-Msieve to see what happens beginning with c5=1M. More if it looks promising.

cubaq 2020-01-12 12:55

thanks....
 
Thank You, RichD.


The example poly is for different one N, sorry if I was not to precise.
Still hope You find something better.
