Congratulation, too. :smile:

EDIT:- Anybody know how to make P95 use a different base to do the PRP test?[/QUOTE]

Congrats. Try adding PRPBase=n to prime.txt.

[QUOTE=axn;385016]There is something to be said for dumb luck.
[CODE]M3464473/604874508299177 is a probable prime! We4: E866B6FC,00000000
[/CODE]
Still need to do some (slow) independent check with PFGW. Ugh!

Congrats. :toot:

If I were you, I would run:

[code]
./pfgw64 -tc -q"(2^3464473-1)/604874508299177"
[/code]

to get a fermat+lucas PRP test done. :smile:

Thanks. That worked (well, it isn't obvious that it worked, so I tried it first on a composite number).

I have already submitted the PRP to the Top list after passing b=5,7 tests, but I will run this as well. The problem is that PFGW doesn't have suspend/resume for these tests, so I'll have to be careful not to shutdown my laptop or interrupt the test in anyway while it runs. Probably will take the better part of a day (or more) to run it, since PFGW uses the generic FFT for them. :sad:

I've just found:

M488,441 = 61543567 x 30051203516986199 x PRP-147012

Anyone up for making: a) a website or b) a codebox on the first post to show what Mersenne numbers have been "fully factored" (PRPs anyways)?

There is already a [URL="http://www.primenumbers.net/prptop/searchform.php?form=%282%5En-1%29%2F%3F&action=Search"]website[/URL].

(edit 2: @Batalov: also on [URL="http://www.mersenne.ca/prp.php"]James'[/URL])

I'm a bit unfamiliar with Probable Primes. How Probable is Probable? Is there a [I]realistic[/I] chance that any of the PRP's for the "fully factored" Mersennes are actually composite?
