For Circular Permutations with unique elements (mirrored ignored) the answer is (n - 1)!/2 (pretty straight forward). However I cant seem to figure out how to calculate circular permutations with repetitions allowed. So the Question is: Given 'm' elements, how many circular permutations (size 'n') with repetitions (mirrored ignored) are there?
