In 1969 , David Barnette conjectured that 3 regular , 3-connected , bipartite , planar graph is Hamiltonian. . I am interested to generate Barnette graph for given even number of vertices. There are countably finite number of Barnette graphs available in the literature.
Consider a grid graph with 4 vertices (cycle C 4) which is Hamiltonian. Increasing dimension in one direction , we see that the resulting graph is always Hamiltonian but not Barnette. Can one generate countably infinite number of Barnette graphs from one small Barnette graph?
