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 .)

This program is used for sieving numbers of some popular
forms that are not supported in NewPGen or any of the other
popular sieves. This includes:
factorials (n!+/-1)
multi-factorials (n!x+/-1 for x > 1, e.g. n!5+1 =
n!!!!!+1)
primorial (p# +/- 1)
Cullens/Woodalls (n*2^n+/-1)
Generalized Cullens/Woodalls (n*b^n+/-1 for b > 2),
x^y+y^x
Cylotomics of factorial/multifactorial form (Phi(a, n!)
and Phi(a, n!x) for a <= 24)
Carol/Kynea (2^n +/- 1)^2 - 2
x^y + y^x
k*b^b +/- 1
Hyper Cullen/Woodall k^b*b^k +/- 1
Near Cullent/Woodall (k +/- 1)*b^k +/- 1
If you desire MultiSieve to sieve for new forms, please

MultiSieve.
