Definitions

A Cullen prime is a Cullen number (n•2n+1), which is prime.

A "Generalized Cullen prime" could be defined as a Cullen prime with a general base b > 2, so of the form nbn+1. The restriction of n+2 > b should then be claimed, otherwise every prime could be called a "Generalized Cullen prime".

Note

For a complete list in this Wiki the primes of the forms nbn+1 are given with b ≥ 2, n ≥ 1 and listed as "Gen Cullen primes".
