# Riesel Prime Search

**Riesel Prime Search** is a prime searching project established in 2005 by Predrag Minovic (Kosmaj).

The project description is as follows:

- The project is searching for Riesel primes k*2^n-1, k>1.
- We have three subprojects as follows.
- (1) k's that can produce many primes in the given range of exponent n,
- (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).
