WebSince it is a linked graph, the possibility of a Hamiltonian route exists inside it. Since none of the graphs in the degree sequence 0,3,1,1 are linked, it is impossible for any of them to have a Hamiltonian route. All graphs with a degree sequence of 0,0,6 are not connected and therefore cannot have a Hamiltonian path.
