Prime divisors of orders of automorphisms and the fixed point subgraphs of automorphisms of prime orders are studied for a hypothetical distance-regular graph with intersection array $\{75,72,1;1,12,75\}$. It is proved that this graph does not vertex-symmetric.
Keywords: distance-regular graph
Mots-clés : automorphism group, antipodal cover.
