Recall that the set of integers mod n, Z/nZ, consists of the n equivalence classes under =. For simplicity of notation, we write Z/nZ = {0,1,2,3,...n-1}. So the element 0 represents the integers that are multiples of n, the element 1 represents the integers that are 1 more than a multiple of n, and so on. List the elements of (Z/15Z)x, the invertible integers mod 15.
