distributed.net - A distributed computing project currently working on RC5-72 and OGR-27 (Optimal Golomb Rulers). Previous projects included CSC and DES. ECMNET - Project to factor numbers using the elliptic curve method. Client and server software. Great Internet Mersenne Prime Search - Online search for Mersenne prime numbers, found largest several primes. Seventeen Or Bust - A distributed attack on the Sierpinski problem, trying to find the last remaining 17 numbers. Goldbach's Conjecture and Factoring the Cryptographic Modulus - Algebraic Factoring of the Cryptography Modulus and Proof of Goldbach's Conjecture Calculating Pi - Investigates and implements algorithms which may yield to distributed computation of the mathematical constant Pi. Generalized Fermat Primes Search - Project provides software to search for primes of a specific form. Coordinated via email. The Prime Sierpinski Problem - Mathematical project to find the smallest prime Sierpinski number. Ellipsa - 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.
