Potential for > applying compression techniques still present. ^^ Per Andreas' last mail, we only need primes up to sqrt(2B) + 1 more. That *has* to be less than 400MB... right? sqrt(2B) = 46340. So the upper limit on the size required to hold all the primes from 2...46340 is 46340*sizeof(int) = 185,360 bytes (plus one more, per Andreas, so 185,364). This is all SWAGing, but I'm assuming the actual number must be *far* less than that... -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
