Definitions
A Woodall prime is a Woodall number (n•2n-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•bn-1. The restriction of n+2 > b should then be claimed, because without this every prime could be called a "Gen. Woodall prime".
For a complete list in this Wiki the primes of the forms n•bn-1 are given with b ≥ 2, n ≥ 1 and listed as "Gen. Woodall primes".
