| Abstract: | Several new constructions for difference matrices are given. One classof constructions uses pairwise balanced designs to develop newdifference matrices over the additive group of GF (q). A second class of constructions gives difference matrices overgroups whose orders are not (necessarily) prime powers. |
| Keywords: | Difference matrices pairwise balanced designs orthogonal arrays |
