hmmm ya know that could be it, i got that riddle from the "car guys" on car talk, ya know that npr show... they seem to like that kind of whacky think.
anyways...

...or sight, of...
incidentally, i know that most of us are not putting these down from memory. where are yall getting your numbers?
edit again! ha! tangent change your answer i beat you to it!! hahaha!

I just wanted to get the list moving a bit faster. Also you got to say "1337" :P

As a matter of fact, Euclid proved about 2.3k years ago that there is an infinite number of prime numbers. However, how big this infinity is (how fast/slow they grow, I guess...), has not yet been discovered, at least that's what a short (and percursory) google search revealed.
Also, patterns in the appearance of prime numbers have been found, but I can't seem to find or recall the article I'm basing this on (but that I'm pretty sure of).

And unless this isn't helpful, here is something that Toshiro was talking about, only it says there is no pattern....

Who?You. I heard NPR's Car-Talk today.
Six --> 3
Twelve --> 6
Fourteen --> 8
Twentytwo --> 9
(it's the number of letters. pretty tricky)
..."are you thinking what I'm thinking?"...

I found the magazine who published the article. But the article is in german and their web-based archive is not free of charge...
Suckage.

Indeed, the number of prime numbers remaining is infinite, give or take a gazillion. A useful resource for you all:

Hm.
I guess I'm just too stupid, but isn't that project (largest odd number search) just a waste of resources? Since there is an infinite number of numbers that are elements of the space |R, even (you know what I mean, all decimals, the one-dimensional space).

Only too true, our maths professor was hardly ever seen coming back from break without a cup of coffee.

I think it's a joke. If a mod 2 = 1, then (a+2) mod 2 will always also equal 1. Modulus arithematic tends to be circular in nature. ;)

That's exactly my point, rogue. Or theirs. They are looking for a number a, so that a mod 2 = 1 and (a+2) mod 2 = 0.
But, as you and I both said, the next odd number logically exists also.
Besides, an edit on my previous post: It's |N, of course, not |R. Silly me.
