Yep, you're right. I ran a 500 block to check it out and mine was 1-2% better. Enough testing. Off to the salt mines...

C166 poly
 

From the OPN list. Can this be tweaked?
It is within the range so don't do too much work on it.

C177_134_73 Poly
 

Can anyone help me with a poly search for C177_134_73, a xyyx stub remaining after yoyo@Home found a factor? I’ve started on the range up to 1M.

For reference, the record e-score for a C177 is held by Max at e=1.448e-13.

What range(s) did you search to date? I can throw some cycles at it later this week.

C177_134_73 Poly
 

I'll take the range 1-2M for the C177 overnight and see where it is at in the morning.

My C166 poly went to 1.5M. It is within the expected range so I'll go with it unless a simple optimization can be performed. (meaning, very little time and effort)

[QUOTE=RichD;482103]I'll take the range 1-2M for the C177 overnight and see where it is at in the morning.[/quote]

Thank you. I’m still plowing through 1-1M, so far no big flares.

Ok. I was going to run 1.5-2M, but if you’re happy with your poly then I’ll leave it alone. Maybe Max will have some luck with his magic.

C166
 

Funny story. If you feed RichD's poly (and the best CADO poly) into msieve, the best you get is:

[/code]Here I list several CADO/msieve polys with the E above 5.697e-013 (some with the scaled c5). I have a feeling you will figure out what to do next.
Also, comparing the top two below, the second best has a better lognorm, better alpha, and better lognorm+alpha, but worse Murphy E. I don't think I ever saw a discrepancy like this before. Handle with care.

The value of N is wrong here. It's a C160 cofactor of 70253804098533303996256039060114483059484940828633741987845788959049023444144179^3-1, not a C177_134_73. The poly is OK though, I am working on it.
