In the mathematical field of graph theory, a prism graph is a graph that has one of the prisms as its skeleton. ==Examples== The individual graphs may be named after the associated solid: * Triangular prism graph – 6 vertices, 9 edges * Cubical graph – 8 vertices, 12 edges * Pentagonal prism graph – 10 vertices, 15 edges * Hexagonal prism graph – 12 vertices, 18 edges * Heptagonal prism graph – 14 vertices, 21 edges * Octagonal prism graph – 16 vertices, 24 edges * ... Although geometrically the star polygons also form the faces of a different sequence of (self-intersecting and non-convex) prismatic polyhedra, the graphs of these star prisms are isomorphic to the prism graphs, and do not form a separate sequence of graphs. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「prism graph」の詳細全文を読む スポンサード リンク
