Let 1, 2, . . . , n be the first row of a Latin square
and 2, 3, . . . , n, 1 the second row. How many candidates are
there

(1) Write down a 3 × 3 matrix, call it A, which is not
triangular (upper or lower) with nonzero deter- minant.
(2) By performing one row operation, change your matrix A into a
matrix B which has determinant 4. (If your matrix A already has
determinant 4, change it to one with determinant 5.)
(3) Compute AB and give the determinant of AB.
