How to help find new 321 primes

Since the establishment of the 321 Search project in April of 2003, the project has relied on The Internet to coordinate people from around the world in search for new 321 primes.

The two main ways to join in the search are: join the forum and use the reservation system; or join PrimeGrid and there select the 321search option. A third way is to email me directly to paulunderwood@mindless.com.

Depending on its speed, a single processor (or core) using PrimeGrid can determine whether a candidate is prime or not in four to nine hours. If instead you reserve at the forum, a manually reserved file of about 58 candidates will take three to four weeks.
