Let u be a positive integer and Z, the residue class ring modulo U. Two subsets D1 and D, of Z, are said to be equivalent if there exist t,seZ, with gcd(t, v)= 1 such that D, = tD, +s. We are interested in the number of equivalence classes of k-subsets of 2, and the number of equivalence classes of
