Automorphisms of Graphs with Intersection Arrays $\{60,45,8;1,12,50\}$ and $\{49,36,8;1,6,42\}$

Automorphisms of distance-regular graphs are considered. It is proved that any graph with the intersection array $\{60,45,8;1,12,50\}$ is not vertex symmetric, and any graph with the intersection array $\{49,36,8;1,6,42\}$ is not edge symmetric.
