Let $\Gamma$ be a strongly regular graph with parameters $(210,95,40,45)$. In this work it is obtained possible orders and subgraphs of fixed points automorphisms of $\Gamma$ in the case, when $[a]$ is a point graph of partial geometry $pG_2(4,9)$ for every vertex $a$ of $\Gamma$.
Ключевые слова:strongly regular graph, automorphism, neighborhood of vertices.
