Lehmer.

positive integers less than or equal to and relatively prime to n. Lehmer’s totient problem consists of determining the set of n such that ϕ(n)|n − 1. Let P denote the set of primes in Z+. It is clear that ϕ(p) = p − 1|p − 1 for all p ∈ P and that ϕ(1) = 1|0 = 1 − 1; however, it is not obvious whether there are any composite n
