## Definitions

A **Woodall prime** is a Woodall number (`n`•2^{n}-1), which is prime.

A **"Generalized Woodall prime"** could be defined as a Woodall prime with a general base *b* > 2, so of the form `n`•`b`^{n}-1.
The restriction of *n*+2 > *b* should then be claimed, otherwise every prime could be called a "Generalized Woodall prime".

## Note

For a complete list in this Wiki the primes of the forms `n`•`b`^{n}-1 are given with *b* ≥ 2, *n* ≥ 1 and listed as "Gen. Woodall primes".
