Riesel Prime Database

The intention of these pages is to collect all known Riesel prime numbers (k · 2n-1 prime, odd k)
and related information like Mersenne primes, twins, Sophie Germain, Woodall (see Glossary).

There are also many data about different projects searching for those primes and their efforts (GIMPS, RPS, NPLB, 321Search, 15k and others).

Especially for beginners in primesearching there are many links, explanations about the programs used and related information.

These pages were created and will be updated by K. Bonath ().

This is the first attempt for a new layout, so there are not all data available yet. They will follow the near future.
