Yep.

It just figures that the P-1 I ran was the useless one since it crashed enough times anyways.... :grin:

T.Rex - Are you producing intermediate residues matching the others? - It would feel a little more safe if you did (although I wouldn't doubt a zero final residue if you didn't).

All the other regulars - Are we close enough to give some more clues? Although the number has more or less been stated to the ones who know how to read the posts here, one could still make a comment comparing how the fake residue of the last exponent was made up (which has been posted in these forums). I would think it would be apropriate to give that clue one day before the confirmation finishes.

T-Rex matches Xyzzy and my residues up to 16M (which is as far as I have checked).

That clue was already given a few pages back.

Also, there is a certain post with some numbers that, if you perform the appropriate calculations, all but reveal the exponent.

There is also a heading which does the same on this page :smile:

I was trying to be unspecifc so newbies or lurkers who don't know the drill won't figure out the exponent and broadcast it to some news agency. But that was what I meant. :smile:

Since its already as good as posted and we will have an official report tomorrow, I'll say that 24036583 is the number. The intrigueing part about it is the interval from 20996011. @3.7 million. If intervals were predictable, we would expect another prime in the 28 to 29 million range. Not much possibility of another prime between M40 and M41 either.

24036583 is the conclusion both Jinydu and I have come to.

jinydu 2004-05-26 01:14

Sigh, I was having such fun trying to guess the exponent using a less trivial method. Anyway, here was the give-away, for those who didn't notice it:

21450000 ( 89.24%) (0.018 sec/iter) (post #204 on this thread)

Therefore:

Secret_Exponent = 21450000/0.8924 = 24036306.

If you read the previous pages, you'll know that that number is very close to one of the candidates: 24036583.

Furthermore, this means that the discoverer is: jfindley

Please don't tell the news agencies until all the verifications are done.
