Abstract: Given a compact connected simple Lie group and a positive integer N relatively prime to the order of the Weyl group we give a counting formula for the number of conjugacy classes of elements x of order N in with the property that the Ncyclotonic field when viewed as a Galois extension of the field of characters of x has Galois group containing a fixed chosen cyclic group . The case recovers a formula, due to Djoković, which counts the number of conjugacy classes of elements of order dividing N in .
