3 Questions:

1) Do you really work for Mercedes-Benz [I sure hope not], or did you somehow get onto your Dad Klaus's computer without his permission?

2) Just how drunk were you when you made these posts?

3) Are you in truth a complete moron, or do you just do a darn good imitation of one?

Is there any "magic" thing you can do that gives you an infinite amount of primes, aside from Euclid's extremely inefficient proof of infinite primes, that gives you primes for any n? If there was, that'd sure be nice, but I don't think there is.

Mini-geek,

There are of course "elementary formulas" which spit out all the primes, and only the primes, in increasing order. However, there are no known formulas which spit out large primes (and only primes) *quickly*.
