"Vertex" is a synonym for a node of a graph, i.e., one of the points on which the graph is defined and which may be connected by graph edges. The terms "point, " "junction, " and 0-simplex are also used. The following tables gives the total numbers of graph vertices for various classes of graphs on n = 1, 2, ... nodes.
