C179 Poly
 

I've completed 8-10M and it is not getting any better. If this can't be spun up then perhaps CADO can achieve the desired results.

Finally broke 9, but I agree maybe CADO is the way forward.

Got CADO running, should have a poly for the C179 by Wednesday night.

Cownoise gives 39090467.79180 for an optimal skew, with an e-score of 1.05512321e-13.

While this value is short of the [url=https://www.mersenneforum.org/showpost.php?p=503952&postcount=134]C179 poly score record[/url], it is not bad wrt the trend line. Certainly better than anything RichD and I found using msieve.

Thanks to RichD and Max for all their work. I played with CADO for another week and found nothing better than that reported above. The job has now been queued in 15e for sieving.

Much appreciated!

C185 Poly needed
 

The latest term in AS 3366 is C185_3366_2194:

[/CODE]

It has undergone ECM up through 28,000 curves @B1=260M.

Any help is appreciated. I’ll reserve 2M < c5 < 4M.

Eta: Point of reference, Msieve is expecting a poly E from 3.98e-14 to > 4.58e-14. The [url=https://www.mersenneforum.org/showpost.php?p=503952&postcount=134]record e-score for a C185[/url] is 4.146e-14.

I'll start at 4M shortly.
