Math. 84, No. 1, 450-453 (2011); translation from Dokl. Akad. Nauk 439, No. 1, 21-24 (2011).} \itemab The authors consider automorphisms of semitriangular graphs with $\mu =7$. Graphs are strongly regular graphs with parameters $(v,k,\lambda,\mu)$ if $v$ is their number of vertices, they are regular graphs of degree $k$, each of their edges lies in exactly $\lambda$ triangles and for any two vertices $a$ and $b$, $\mu(a,b)$ is $\left|\left[a\right] \cap \left[b\right]\right|$, where $\left[a\right]$ and $\left[b\right]$ denote the neighborhoods of two nonadjacent vertices $a$ and $b$. For strong regular graphs $\mu (a,b)$ does not depend $a$ and $b$. The authors find possible automorphisms of semitriangular graph with $\mu =7$ and subgraphs of their fixed points. \itemrv{I. M.
