That means it's almost certainly larger than the false M40.

I mean, the progress of the final verification.

I probably did the math wrong, but I think the range is from 216609641-1 through 233219277-1...

I am thinking M20.2-M20.6ish, because that is where most of the exponents are being checked in.

In the wake of the false prime report a few months ago, we added a few failsafes to quickly detect a false report. Fortunately, this user was using the new version of prime95. He emailed me the save file with 2000 iterations remaining. I reran those final iterations and my computer also reports this number prime - in my mind eliminating any chance of a hardware error.

Unfortunately, we still must go through the official different machine, different program verification which will probably end in early December. So please be patient awaiting the disclosure of the number. Waiting for verification saved us from a huge embarrassment last time!

Oh yes, hints. I've always given hints. The prime number is more than five million digits and less than ten million digits.
Which is to be expected.

By the way, another advantage of the "rerun last few thousand iterations" idea is that it makes it *very* hard to forge a prime result - probably in my mind computationally infeasible - even if you break the security code.

Hey, just so you know, I am still around :). I read the mailing list and still occasionally check the forum. This is great news. Congratulations to the winner and everyone else who as participated by running Prime95. Also, thank you George for your great software :).

That is all I have to say, I'll see you guys later.

Andrew

PS: This is exciting!

I probably did my calculations wrong, too, but here is my prediction:

exponent of new mersenne prime is from range M17.8 - M23.2.

We could organize betting on this subject.

Really, this is so exciting!

/edit - Did you notice interesting feature of date when new Mersenne prime is discovered? 17-11-2003! 17 - PRIME!, 11 - PRIME!, 2003 - PRIME! BINGO!!! This was really our lucky day!

Could anyone tell me when did the Primenet server start to assign 18M/19M/20M/21M/22M+ exponents?

That topic already appeared in the news (in German) of the popular german computer magazine "c't":
http://www.heise.de/newsticker/data/as-18.11.03-000/

(It's the same mag that tested Prime95 on Opteron in april)

I don't suppose "insider betting" is allowed
