Advances and Applications in Discrete Mathematics

Abstract:
A recurrent method for constructing difference matrices

has been constructed under the condition that both the difference matrix

and the orthogonal array

are known. Some new difference matrices with non-prime power levels, such as

have also been constructed.

Keywords and phrases: difference matrix, generalized Hadamard matrix, orthogonal array, permutation matrix, projection matrix, Kronecker sum.
