A titan, as defined by Samuel Yates, is anyone who has found
a titanic prime. This page provides data on those that have found these primes. The data below only reflect on the primes currently on the list. (Many of the terms that are used here are explained on another page.)

The "Riesel Prime Search" project is searching for Riesel
primes k*2^n-1, k>1. We have three subprojects as
(1) k's that can produce many primes in the given range of
(2) low-weight k's that produce a very small number of
primes [opposite to (1) above],
(3) small k < 300 (with exception of those k's already
reserved by other projects).
How To Join
Everybody is welcome to join the project. Just visit the
forum link given above, have a look what's going on, and
reserve your first file to test!
Primality Testing: LLR. pfgw and Proth.exe used
for small exponents (less than 10k or 20k) and for
Sieving: srsieve and NewPGen.
