The Kneser graph K(n,k) has as vertices the k-subsets of {1,2, . . .,n}. Two vertices are
adjacent if the corresponding k-subsets are disjoint. It was recently proved by the first
author [2] that Kneser graphs have Hamilton cycles for n ≥ 3k. In this note, we give a
short proof for the case when k divides n.
