Cownoise gives 27015811.43318 and 1.71407315e-14 for this result. Per the GNFS poly score records page, it appears a score of 2.3e-14 to 2.5e-14 is the sweet spot for a c190.


I am currently searching a5 range 15-17M using msieve-gpu. Unfortunately all my CADO machines are tasked with the c203 poly search posted above in this thread so my progress on this search will be glacial. Blind squirrels and nuts!

I still can't get a 2-handle. My 10M range is still running.

Nothing better. I'll run a5=6-8M tonight on msieve-gpu.

I'm not getting anything better than a 1.6. One more last attempt. Can any of the previous polys be spun?

I'll try the spin script against the last few a little later tonight and see what may show up by tomorrow.
