Riesel and Proth Prime Database (RPPDb)
ATTENTION: The tables on Riesel Prime Search are outdated (only for k < 300 updated) and not under my control.The intention of these pages is to collect all known Riesel (k · 2n-1, odd k) and Proth (k · 2n+1, odd k) prime numbers
and related information like Mersenne primes, twins, Sophie Germain or Woodall.
There are also many data about different projects searching for those primes and their efforts (GIMPS, RPS, NPLB, 321Search, 15k and others).
These pages were created and will be updated by K. Bonath ().
For reserving and reporting your progress on Riesel-numbers see also the Forum at Mersenne.org.
