No, I meant the largest unknown prime. > http://primes.utm.edu/infinity.shtml <quote> About 2000 years ago Euclid proved that there were infinitely many primes. For mathematicians "infinity many" is an incomplete answer--they then ask "how big of an infinity?" The prime number theorem, which states the number of primes less than x is approximately x/log x (the natural log), gives perhaps the best answer. ...... the sum of the reciprocals of the primes diverges, so the primes are a "large" subset of the integers </quote> -- Stuart
