Апстракт


A connected graph G is Hamiltonian-t-laceable if there exists in
it a Hamiltonian path between at least one pair of distinct vertices u and v with the property d(u; v) = t; 1 6 t 6 diamG. G is termed t-connected if it is Hamiltonian-t-laceable for all t. In this paper, we show that the modied distance graph of the grid graph Mgr(m; n) for n = m, 4 < m < 11 and for n = 2m, 2 < m < 8 is t-connected.
