Recently it was shown that a distance-regular graph in which neighbourhoods of vertices are strongly regular with parameters (99,14,1,2) has intersection array $\{99,84,1;1,14,99\}$, $\{99,84,1;1,12,99\}$ or $\{99,84,30;1,6,54\}$. In the present paper we find possible automorphisms of a graph with the intersection array $\{99,84,30;1,6,54\}$. It is shown, in particular, that such a graph is not point-symmetric.
Keywords: distance-regular graph, strongly regular graph, automorphism of a graph.
