Автоморфизмы графа с массивом пересечений $\{169,126,1;1,42,169\}$

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 $\{169,126,1;1,42,169\}$. It is obtained the description of vertex-transitive distance-regular graph with intersection array $\{169,126,1;1,42,169\}$ and nonsovable automorphism group.
