**Title: ** Representations of graphs and orthogonal Latin square graphs. (In English)

**Source: ** J. Graph Theory 13, No.5, 593-595 (1989).

**Review: ** We define graph representations modulo integers and prove that any finite graph has a representation modulo some integer. We use this to obtain a new, simpler proof of Lindner, E. Mendelsohn, N. Mendelsohn, and Wolk's result that any finite graph can be represented as an orthogonal Latin square graph.
