Abstract: A connected graph G = (V, E) is called Hamiltonian if G contains a spanning cycle and if a graph G contains a spanning path between arbitrary pair of its vertices is called Hamilton-connected. A bipartite graph is called Hamilton-laceable if there exist Hamiltonian path between vertices of different partite sets and a graph G is random Hamiltonian- t* – laceable if there exists a u – v Hamiltonian path for at least one pair u, v ɛ V(G) for t* distance. In this paper, we have studied the Hamiltonian laceble and random Hamiltonian-t*– laceable graphs of total transformation graph G-++ of graphs viz. path Pn, cycle Cn, complete bipartite graph K, n-dimensional convex polytopes Dn, Hn and Gn.  

Keywords: Hamiltonian graph, Hamiltonian connected, Hamilton-laceable, total transformation graph.
