Let Rn be the group of rotations of a regular pentagon, and let r be counterclockwise rotation by the angle (27/n). a) Find all generators of R5 (if any). Express your answers in terms of r. b) For n> 3, find all generators of Rn (if any). Express your answer in terms of r. Explain your answer. ('Explain' here means you don't necessarily have to write out a complete proof, but you must give a convincing argument for why your answer is correct.)
