Now, a c164.

[code]2477. 229836343198830452904906926072687726445274504040590457858093954259846740197541450378930115385305580707404985478037205666706877074351759707192765877028347973091075810594208 = 2^5 * 13 * 34031 * c164

We have a moment of truth.
2^5 * c169

that is by far larger than this forum has done
can we do it?

Let's hope it cracks, but if not... there's nothing to it :whistle: --
Womack+mersenneforum had done a gnfs-180, as you know.

i meant the aliquot forum

First, a lot of ECM.

Anyone like the idea of doing it in the Factoring forum to get more attention? (First I would have to get mod powers there, but I'll only ask for them if I need to.)

Meanwhile I'll run some curves on it at 3e6 (guessing SB has already done t35)...

BTW, I think we would need to ECM to about t55. OK?

i think most the major hitters read this forum

I do not think that would be necessary.

Doing 2000@4e7 overnight.

OK, agreed. I had forgotten that Mersenneforum+Womack has come to an end (or so we expect).
