Default 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.
Code:

R1: 44596742390301593

A3: -14847487943043286222040
A4: 95055565562130
A5: 8659980
skew 22749253.63, size 1.373e-17, alpha -7.009, combined = 8.570e-14 rroots = 5

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

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

While this value is short of the C179 poly score record, 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!

Default C185 Poly needed

The latest term in AS 3366 is C185_3366_2194:

Code:
48427554071403254933544130089025533493522277589651092400710320434290160236946644598408857040687162164459028084658660898215945794349265273715322667428371645490246209893863263844759204579
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 record e-score for a C185 is 4.146e-14.
