) The set {1,2,..., 22} is to be split into two disjoint non-empty sets S
and T in such a way that:
(i) the product (mod 23) of any two elements of S lies in S;
(ii) the product (mod 23) of any two elements of T lies in S;
(iii) the product (mod 23) of any element of S and any element of T
lies in T.
Prove that the only solution is
S = {1, 2, 3, 4, 6, 8, 9, 12, 13, 16, 18},
T= {5, 7, 10, 11, 14, 15, 17, 19, 20, 21, 22}.
