A note on the automorphism group of the Hamming graph

Let $Ω$ be a $m$-set, where $m>1$, is an integer. The Hamming graph $H(n,m)$, has $Ω^{n}$ as its vertex-set, with two vertices are adjacent if and only if they differ in exactly one coordinate. In this paper, we provide a proof on the automorphism group of the Hamming graph $H(n,m)$, by using elementary facts of group theory and graph theory.
