, p_k), then phi(m*n) = (Product_ A(x^k). Using the number theoretic function Euler totient function we have defined an Euler totient Cayley graph and in this paper we study the Clique domination. Suppose that a and n are coprime positive integers, then by Euler's totient theorem, any factor of n divides a^phi(n) - 1.

Benoit Jubin, Aug 09 2008Ī(n+2) equals the number of palindromic Sturmian words of length n which are "bispecial", prefix or suffix of two Sturmian words of length n + 1. The totient function also plays a key role in the definition of the RSA encryption system. Number of automorphisms of the cyclic group of order n.
For n > 2, a(n)/2 = A023022(n) = number of partitions of n into 2 ordered relatively prime parts. Also known as Euler’s totient function counts the positive integers up to a given integer n that are relatively prime (two integers are coprime, relatively prime, or.
