Small Regular Graphs with Four Eigenvalues

van Dam, Edwin Robert; Spence, E. - Tilburg University, School of Economics and Management - 1996

For most feasible spectra of connected regular graphs with four distinct eigenvalues and at most 30 vertices we find all such graphs, using both theoretic and computer results.

The Search for Pseudo Orthogonal Latin Squares of Order Six

Bussemaker, F.C.; Haemers, W.H.; Spence, E. - Tilburg University, School of Economics and Management - 1999

We report on the complete computer search for a strongly regular graph with parameters (36,15,6,6) and chromatic number six. The result is that no such graph exists.
