Abstract

A cyclic Latin square of order 2ⁿ, which has no orthogonal Latin square mate, is shown to have (2ⁿ-1)(2ⁿ-2) mutually orthogonal F(2ⁿ;2^n-1,2^n-1)-squares. This is a complete set of F-squares for the cyclic Latin square. Row and column operations areused to construct this complete set of F-squares from a Hadamard matrix and 2ⁿ-1 OF(2ⁿ;2^n-1,2^n-1)-squares into which the Latin square is decomposed. Tables of complete sets of mutually orthogonal F(2ⁿ;2^n-1,2^n-1)-squares are given for n=2 and 3, i.e., for cyclic Latin squares of orders 4 and 8.
