Summing up the Euler [phi] Function
Loomis, Paul; Plytage, Michael; Polhill, John
College Mathematics Journal, v39 n1 p34-42 Jan 2008
The Euler [phi] function counts the number of positive integers less than and relatively prime to a positive integer n. Here we look at perfect totient numbers, number for which [phi](n) + [phi]([phi](n)) + [phi]([phi]([phi](n))) + ... + 1 = n.
