primenumbers : Prime numbers and primality testing

Activity within 7 days:

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 prime numbers, primality testing, and very closely related subjects.

If you enjoy prime numbers there are similar lists you might enjoy, such as PrimeForm focusing on primality proving programs and GIMPS' Mersenne Primes list.

If you think you have a Goldbach proof, then please note that there are groups which deal specifically with such matters, perhaps try those first?

[ The Prime Pages : FAQ | Glossary | Links | Top 5000 | CrackPots ]

Avoid sending the same mail to multiple lists! (because it spams those who are on all of them).
Follow links at you (on left) at your own risk! They have been provided by the members. We check them periodically but...
Also download files (on left) at your own risk. Is your virus checker up to date?
Please report any malicious or non-prime related files/links/... to the moderators.
