The 321 Search Project goals

The project has many objectives. The first and most important is to discover new 321 primes. The project will hopefully find a prime number with more than 1 million digits. Update: This was achieved on 23rd March 2008.

We keep a record of every test done so others can double-check our work for errors or check their own computer or software for errors. Eventually we hope to have for each possible 321 number either its divisor or its LLR (Lucas Lehmer Riesel) 64 bit residue. This will cover 321 numbers from 3 bits to 5,000,000 bits.
