Welcome to the Year of the Snake Challenge
4 January 2013 18:00 UTC --> 17 January 2013 18:00 UTC.

Special Note: This is the second ever GFN challenge and probably the last, so for those who are not familiar with GFN we are searching for exceptionally large prime numbers. If a prime is found during the challenge it will be the 11th largest prime number ever found. In fact, we found a new GFN prime just two days before the start of the challenge! Let's find one or two more!

A 13 day Challenge celebrating the start of a new year is being offered on PrimeGrid's Generalized Fermat Number (GFN) application. Only SHORT Work Units may be used in this challenge. To participate in the Challenge, please select only the Generalized Fermat Prime Search project and also select Short tasks in your PrimeGrid preferences section. Although the World Record units can also be completed within 13 days, these do not count! You may leave the Block Size setting at 0.
