Early raw CADO result. The skew needs to be optimized by cownoise.com. It looks that I can make it better.

A flare though with a sizable skew. Maybe Max can weave some magic.

Nothing good found in rest of my range.

Reserving 1-4M.

I’ve finished searching c5<4M but found nothing else worth posting. Not sure how much more searching is desired. Was hoping to find a score with a 9-handle but we might need to search a much larger range (and get lucky) to find it. The best score chart says we have exceeded the best score of a C181.

Is anyone working CADO?

This poly is very good, I think we can finish search now.

I'm interested in getting msieve on my GPU running.

I want to factor a bunch of c150-c165s which seems very achievable with my 2x Xeon machine.

Ultimately I'd like to factor

http://factordb.com/index.php?showid...00000899019947
n = 603289266890589216703233577063528121991341644185218188935827689203288886693381218001456864721430619722495427891807584275878382343140356574834475435042519455503292387

But I think it would be better to start with

http://factordb.com/index.php?id=1100000000130206405

n = 9802463953973485517888552567159433034689508794240241805713893649484774212190173820071569371185096203579675693594637332591457306735786962072348449116391

If someone could generate me an okay poly for either one and share the commands they used I'd appreciate being able to verify the same results.
