We found the possible orders and the structures of subgraphs of the fixed points of automorphisms of strongly regular graph with parameters $(396,135,30,54)$. These results can be used to study automorphisms of strongly regular graph with parameters $(640,243,66,108)$ (in such a graph the second neighborhood of vertices are strongly regular with parameters $(396,135,30,54)$).
