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)
LLR takes an input file from Paul Jobling's NewPgen, and proves the primality of numbers of the form k.2n+ 1 with k < 2n. It implements the Lucas-Lehmer-Riesel and Proth algorithms, using George Woltman's gwnums and assembly code routines for fast multiplications and squarings.
