Abstract
It is known to be a hard problem to compute the competition number k(G) of a graph G in general. Park and Sano [13] gave the exact values of the competition numbers of Hamming graphs H(n,q) if or . In this paper, we give an explicit formula of the competition numbers of ternary Hamming graphs.
