In combinatorics, an area of mathematics, graph enumeration describes a class of combinatorial enumeration problems in which one must count undirected or directed graphs of certain types, typically as a function of the number of vertices of the graph. These problems may be solved either exactly (as an … See more In some graphical enumeration problems, the vertices of the graph are considered to be labeled in such a way as to be distinguishable from each other, while in other problems any permutation of the vertices is … See more Some important results in this area include the following. • The number of labeled n-vertex simple undirected graphs is 2 . • The number of labeled n-vertex simple directed graphs is 2 .

WebMar 24, 2024 · An n-polyhedral graph (sometimes called a c-net) is a 3-connected simple planar graph on n nodes. Every convex polyhedron can be represented in the plane or on the surface of a sphere by a 3-connected planar graph. Conversely, by a theorem of Steinitz as restated by Grünbaum (2003, p. 235), every 3-connected planar graph can be … WebSequences from Harary and Palmer's Graphical Enumeration The On-Line Encyclopedia of Integer Sequences Sequences from Harary and Palmer's Graphical Enumeration Keywords: Harary, Palmer, graphs, counting, enumeration, integer …
