Site updated.
Congratulations on your find gribozavr! :bow:

That's a juicy pair, Dmitri!

M332193233 from 64 to 71 bits with mfactor. No factors found.

gribozavr 2005-11-12 10:31

M332193109 from 67 to 70 bits with mfactor. No factors found.

gribozavr 2005-11-13 14:02

M332192969 from 70 to 71 bits with mfactor. No factors found. 1193 minutes.
M332193859 from 64 to 65 bits with mfactor. No factors found. 25 minutes.


I wonder, is there some "goal" bit depth? What maximum bit depth makes sense for 100MDPP?

Gribozavr's on a row! I'll release my exponent on 64 bits, feel free to find a factor for it!

Wow...

I don't think I'm the one to ask... :unsure: . It was because the project seemed dead that I took it over. I have a bit of knowledge about what this project is regarding (remove as many candidates as possible) but I don't know where to stop.

We could keep going until we find a factor (or waste a bunch of CPU cycles on a prime)
Or we could do as OBD and say that we run 'X' candidates to 'Z' bits.

What do you people want? :whistle:
