Default Poll: When will the first Centamegaprime drop?

Since a poll can't be added to this thread.

Simple poll.

When will the first 100,000,000 digit long prime number be found, any type, by anyone?

For the sake of things, assume that it can be verified within a reasonable time frame.

Hm, doesn't this thread bear a striking resemblance to this thread here?
http://www.mersenneforum.org/showthread.php?t=10652
Edit: Nevermind, ignore this, this one has a poll and the other doesn't (the first post didn't say that when I first posted).

Looks like the trolls have been busy. They left no fingerprints this time.
Those post are highly encouraged.

That is, an exponent greater than 332192810.

Not necessarily. If it's a k*2^n+-1 with a large k, the exponent could be quite a bit smaller. If it's a completely different form, including k*b^n+c with a b>2, the exponent could be much smaller.

Well... sure, but with Mersenne primes occupying the top 8 slots, and no good algorithm for discovering large non-Mersenne primes, it seems likely that the first 100M would be Mersenne.

But even if not, knowing the Mersenne exponent equivalent is useful for comparison purposes. Obviously the exponent of a Mersenne prime need not correspond at all to the exponent of a prime of a different form.

Oh, I agree that it's very likely (unless some big new discovery comes out between now and it) the first 100M digit prime would be Mersenne, just pointing it out that it's not necessarily Mersenne.

Ha. I'm going to find a 100M digit non-mersenne k*b^n±c prime just to spite everyone.

See you in 10 years.

Going troll hunting.
The gerbils are next (I got a Bill Murray signature Ghostbusters Backpack), then the snake.
