A number n falls into this category if its Euler quotient function value equals n minus one.
A number n falls into this category if its Euler quotient function value equals n minus one. Algorithms to approximate testing for these include the square root of one test, an algorithm based upon Fermat's Little Theorem that always fails for Carmichael numbers, and the Miller-Rabin algorithm. Large ones are typically used in cryptography algorithms such as RSA. FTP, name this type of integer whose subvarients include the Fermat and Mersenne types, distinguished by having two divisors, itself and one.
