inverse of Euler's totient function
The InverseTotient function returns the inverse image of Euler's totient function.
Given a positive integer m, InverseTotient(m) returns the set of integers n that satisfy the equation Totient(n) = m.
There are no numbers besides 1 and 2 with an odd totient.
The following command plots the points (m, n), where n is a member of InverseTotient(m), for m from 1 to 1000.
The NumberTheory[InverseTotient] command was introduced in Maple 2016.
