A cubic polyhedral graph is a graph that is both cubic and polyhedral. The numbers of cubic polyhedral graphs on , 4, ... nodes are 0, 1,
1, 2, 5, 14, 50, 233, 1249, ... (OEIS A000109).
The following table summarizes some named cubic polyhedral graphs and classes of graphs, some of which are illustrated above.
Tabulations of cubic polyhedral graphs are commonly limited to those that are triangle-free (e.g., Read and Wilson 1998). The
numbers of -node triangle-free
cubic polyhedral graphs on
, 2, ... nodes are 0, 0,
0, 1, 1, 2, 5, 12, 34, (OEIS A000103).
The figure above illustrates triangle-free cubic polyhedral graphs up to 18 vertices, together with their notation in Read and Wilson (1998).
