GIMPS (http://mersenne.org) have just found a probable prime. It is being double-checked right now. They expect it will be finished by June 21st. How long do you think it will be?

I put 7M to 10M, I'm just guessing this from the time they're taking to verify it!

"Woo hoo! It looks like the 40th Mersenne prime has been found. It is larger than M13466917, but it is not a 10 million digit prime. " -GW

so it's got to be up there.

oops, didn't see that!
Well, I guess the only question now is if it's more or less than 7M!

If I recall the list correctly, the three highest ones have something in the neighborhood of 1M, 2M and 4M digits, so I'll say this one will be 8M (+/- 10% or so) just because it would look nice.

GIMPS is currently testing exponents near 20,000,000 - so you can be sure the new find is under 6 million digits.

my guess is it's something between 5.7m to 5.8m digits. ;)

From mersenneforum.orgWoo hoo! It looks like the 40th Mersenne prime has been found. It is larger than M13466917, but it is not a 10 million digit prime.

So this is an easy poll

I know, some have still gone wrong, though ;)
The reason this is so easy is because I posted it before GIMPS annouced anything interesting about the prmie!

I just pulled this off the GIMPS homepage:

"40th Mersenne prime not found On June 1st a possible Mersenne prime was reported to the server. Unfortunately, two independent verification runs proved the number was composite. This was the first false positive report in 7 years. We are studying ways to reduce the chance that cpu or memory errors can cause a false positive report."

:(

I was so excited for Woltman and GIMPS.

That's a pity. :(

Well, what can I say more? Although it would have made it harder for SB to get the largest prime, it's sad anyway that this extreme reward fot their effort did not occur...
