Let G be a connected graph and T be a spanning tree of G. For e ∈ E(T ), the congestion of e is the number of edges in G joining the two components of T − e. The congestion of T is the maximum congestion over all edges in T . The spanning tree congestion of G is the minimum congestion over all its spanning trees. In this paper, we determine the spanning tree congestion of the rook’s graph Km Kn for any m and n.
