The search for pseudo orthogonal Latin squares of order six. (English) Zbl 0985.05011
The paper describes the results of a computer search for a strongly regular graph on 36 vertices, degree 15, \(\lambda= \mu=6\) with chromatic number 6. It is shown that no such graph exists. The result can be interpreted also in terms of pseudo-orthogonal Latin squares of order 6.
