program A titan, as defined by Samuel Yates, is anyone who has found a titanic prime. This page provides data on those that have found these primes. The data below only reflect on the primes currently on the list. (Many of the terms that are used here are explained on another page.)

Descriptive Data: (report abuse)
Please link to this code whenever using FermFact as a trial factoring program. FermFact is a "rectangluar" range, Base-2 proth siever. It is ideal for trial factoring ranges of k*2^n+1 numbers for later testing for primality, and possible Fermat or GF divisibility (hense the name FermFact). The latest software version of FermFact can be found in the files folder of the primeform Yahoo group. This location is: http://groups.yahoo.com/group/primeform/files/Sieving Programs/
