EC#1 Show that the number of different circular arrangements of the n{“version”:”1.1″,”math”:”n”} objects is (n-1)!{“version”:”1.1″,”math”:”(n-1)!”}. Use the following arrangements of the five letters A, B, C, D and E in the accompanying figure. The permutations ABCDE, BCDEA, CDEAB, DEABC, and EABCD are not distinguishable. Generalize this observation to the case of n{“version”:”1.1″,”math”:”n”} objects.
