• distance-regular graph
• automorphism
• vertex-transitive graph

A description is furnished for automorphisms of prime order and subgraphs of their fixed points in distance-regular graphs with intersection arrays {50, 42, 1; 1, 2, 50} and {50, 42, 9; 1, 2, 42}. It is proved that these graphs cannot be vertex-transitive.
