Timeline for Is there a formula to count how many different topological regular maps can be created with n faces (on a sphere)?

| Apr 21, 2011 at 7:16 | comment | added | Mario Stefanutti | I made a correction to the question (as pointed out by jc). I was interested in "regular maps" without forcing 3-vertex-connectivity. Sorry for the mistake. The abstract of the paper reports: "In the paper, we enumerate three classes of cubic planar maps with no loops or multiple edges: 1-connected; 2-connected; 3-connected and triangle-free." The results I found manually give these results for 3, 4 and 5 faces: 1 maps, 3 maps, 20 maps. | |
