Purpose

The goal of this project is to find Generalized Cullen primes of the form nbn+1 for bases b which have no known primes.

Status

The bases currently being searched by the project:

Found primes

Each of these finds was the first known Generalized Cullen prime in that base, eliminating that base from the search.
