A m x k matrix A, with entries from a set ofq => 2 elements, is called an orthogonal array OA(m, k, q, t) (t > 2) if each m x t submatrix of A contains all possible 1 x t row vectors with the same frequency 2(m = 2qt). We call the array schematic if the set of rows of A forms an association scheme with the relations determined by the Hamming distance. In… (More)
