Online search for Mersenne prime numbers, found largest several primes.

A distributed attack on the Sierpinski problem, trying to find the last remaining 17 numbers.

A distributed computing project currently working on RC5-72 and OGR-27 (Optimal Golomb Rulers). Previous projects included CSC and DES.

Project to factor numbers using the elliptic curve method. Client and server software.

Primo, a primality proving program based on the ECPP algorithm. With Primo one can check crypto-primes and prove whether or not they are actually prime.

Mathematical project to find the smallest prime Sierpinski number.

Investigates and implements algorithms which may yield to distributed computation of the mathematical constant Pi.

Project provides software to search for primes of a specific form. Coordinated via email.
