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)
SoBSieve is a program written by Paul Jobling to help with the Seventeen Or Bust search to eliminate candidate Sierpinski primes (see www.seventeenorbust.com for more details). It works by removing those n where k_i.2^n+1 is composite, where k_i is one of the remaining Sierpinski candidates.
