project 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.)

The Twin Prime Search (TPS) is a distributed computing project that searches for large twin primes. It was founded on April 13 2006 by Michael Kwok, and it has found two twin primes that were the largest in the world at the time of discovery. It worked in collaboration with PrimeGrid from November 2006 - August 2009.

TPS currently works on two projects: a variable-n search that looks for twins between 144,000 and 151,000 digits long, and a subproject called "Operation Megabit Twin" that searches for twins and Sophie Germain primes that are over a million binary digits long. Primality testing can be done automatically using LLRnet and/or PRPnet, and sieving is done through manual reservations. See this thread for further information:

Happy prime (and twin) hunting!
