The Prime Pages: Conjectures 'R Us

Conjectures 'R Us
(Another of the Prime Pages' resources)

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)

Our project aims to prove many of the Riesel and Sierpinski conjectures for bases 2 thru 1024 that are not currently being worked on by other projects or efforts.

Definition:
For every base (b) for the forms k*b^n+1 and k*b^n-1, there exists a k-value for each form that is conjectured to be the lowest 'Sierpinski value' (+1 form) or 'Riesel value' (-1) that is composite for all values of n >= 1.

k's that have a trivial factor (one factor the same) for all n-values as well as k's that make Generalized Fermat #'s are not considered.
