[QUOTE=Christenson;265102]Indeed...another factor!

I have no such good news to report:

no factor for M3321933541 from 2^80 to 2^81 [mfaktc 0.17-Win barrett92_mul32]

Validation only:
no factor for M3321933397 from 2^72 to 2^73 [mfaktc 0.17-Win barrett79_mul32]
no factor for M3321933397 from 2^73 to 2^74 [mfaktc 0.17-Win barrett79_mul32]
no factor for M3321933397 from 2^74 to 2^75 [mfaktc 0.17-Win barrett79_mul32]

Just for fun, extending the validation:
no factor for M3321933397 from 2^75 to 2^76 [mfaktc 0.17-Win barrett79_mul32]
no factor for M3321933397 from 2^76 to 2^77 [mfaktc 0.17-Win barrett79_mul32]

Do you still plan to take M3321933397 to 81 bits?

Luigi

Yes, I'm still taking
M3321933397 to 81 bits.....
then I'll put that GPU back to more *serious*:mike: OBD work....
But I don't think anyone else is silly enough to do that right now.
