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

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

Attempt at factoring the huge Mersenne number 2^(2^61-1)-1. Software for Windows, DOS and Linux. Work reservation via email.

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.

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

Distributed project to help solve the Riesel problem through the use of donated unused CPU cycles.

Mathematical project to find the smallest prime Sierpinski number.

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

A distributed computing project currently trying to take the RSA challenge of RC5-64, and also working on OGR-24 and 25 (Optimal Golomb Rulers). Previous projects included CSC and DES.

Monetary prizes for factoring certain large numbers ("RSA Numbers"), as well as breaking RSA and DES encryption schemes; announcements mailing list.
