of quasi-difference matrices over difference matrices to obtain orthogonal arrays with given parameters. We also study … the existence of quasi-difference matrices over cyclic groups originating orthogonal arrays with t=2 and λ=1, proving …-difference matrices and also a Bimodal Local Search algorithm to obtain them. We provide a conjecture related to the distributions of …
