# Rigid Strongly Regular Graphs

I need a few examples of graphs that are strongly regular as well as rigid, i.e., have only the trivial automorphism. Any references to relevant literature would be appreciated. Thanks.

You get more examples as Latin square graphs. Take an $n\times n$ Latin square (with $n\ge 6$). Define the vertices of the graph to be the $n^2$ cells of the square, and declare two cells to be adjacent if they are in the same row, or in the same column, or have the same content. Most Latin squares will work.
