I find it kind of coincidentally humorous that this thread began the day after a show called Numb3rs aired an episode (Guest starring Doogie Howser:) ) about Riemann's Hypothesis, and number sieves to extrapolate large prime factors from encryption keys..  But I must point out that they even failed on tv..

I agree, let's just forget about doing any math and just start guessing numbers

Ok, thats the second user with an account probably created solely to maniplulate this thread..  The other one (triggernum6) baffles me since I can't understand why somebody would try to mimick my name and not do anything with it..

I added the word 'probably' incase that was the reason..  As far as your optimism goes I commend it, but it does seem that the ppl posting relevant info here are on the pessimistic side to say the very least..  Even with the entire universe acting as a quantum computer that list of primes could not be stored..

I hope you are not talking about me. I'm a long time reader of Xbox-Scene and when I saw these guys making rude comments I decided to finally make an account and defend the innocent.

Ill make this simple. You want to see update. You pm me. Ill make a small forum just for this post. That way I can idiots who arnt interested and want to be asses.
If you have already been a part of this thread I will add you and send you a pm with the url for this in a little bit.

BTW. To the guy who said you cannot store a list of all the prime numbers under 617 digets. My professor at USC is sending me 140+ dvds with THE LIST! I am right now building a beowoulf cluster for it. Well more or less, Im not building it but a group from work is helping me with it.

for instance, (2^25,964,951)-1 is over 7 million digits long, however in the form i just wrote out, it's quite a bit more manageable. also i think some of the other math done before was a little shady....oh well though.

If the approximation of primes under the root is accurate at ~6.0286674e307 then it doesn't matter what notation you use, you don't have enough storage space in the universe.. If the equation crumbles then maybe they can fit on dvds, I dunno..

Those primes were you can simply subtract one from a number raised to an exponent are called mersenne primes, and while there are a lot of them, there are far more non-mersenne primes (more than would fit on the individual atoms of 140 dvds).

Even if you were to assume that it would take 32 bits to represent a number like that (2 chars and an int), using the exact (well, ± 1) number of primes <= 10^23 (far less than what we're working with), it would still take (1925320391606818006727 * 32) / 8) / 1024 / 1024 / 1024 / 1024 = (approximately) 7004274780 terabytes. Now, I do believe that 140 dvds is still far less than that, and that he's working with far more numbers. Just storing the numbers <= 10^23 would take about 1526037740000 dvds

primes are inherently unpredictable (like noise is) so they do not compress well.  if they did, they'd be no good for encryption.
