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 *N*-cyclotonic 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 .
