A203907: Successor function for Conway's PRIMEGAME.

{ 55, 15, 165, 30, 275, 45, 1, 60, 495, ... }

This sequence demonstrates that Conway's prime producing "machine" never stops working. Whatever integer is input, one of two things will happen: either the machine will take us on a roller-coaster ride towards a power of 2 with a prime exponent, or get stuck on an infinite loop between two values. But never will it happen that the machine receives an integer and refuses to do anything to it.
