Group Description

PrimeNumbers is a e-mail discussion list for those
who enjoy prime numbers.  Some look for patterns,
some seek to find new records, others try to understand
the distribution.  We try to limit our discussion to

Primes list.

  • Also download files (on left) at your own risk.  Is your virus checker up to date?
