A Woodall number is defined to be a number of the form If a prime number can be written in this form, it is then called a Woodall prime. The generalized Woodall numbers and generalized Woodall primes substitute any base for the base 2.
Woodall first announced his work on factorization in a 1911 publication, acknowledging in it his communication on the subject with Allan J. C. Cunningham.[3] In 1925 Cunningham and Woodall gathered together all that was known about the primality and factorization of the Woodall numbers and the generalized Woodall numbers with base 10, and published a small book of tables. Since then many mathematicians have continued the work of filling in these tables.[4]
