Abstract:
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, automorphism group, antipodal cover.
