(Generalized) Cullen primes

From Prime-Wiki
Jump to: navigation, search


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".


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