In four-dimensional geometry, a cantellated 120-cell is a convex uniform 4-polytope, being a cantellation (a 2nd order truncation) of the regular 120-cell. There are four degrees of cantellations of the 120-cell including with permutations truncations. Two are expressed relative to the dual 600-cell. ==Cantellated 120-cell== +720 |- |bgcolor=#e7dcc3|Edges||10800 |- |bgcolor=#e7dcc3|Vertices||3600 |- |bgcolor=#e7dcc3|Vertex figure|| wedge |- |bgcolor=#e7dcc3|Schläfli symbol|| t0,2 |- |bgcolor=#e7dcc3|Symmetry group||H4, (), order 14400 |- |bgcolor=#e7dcc3|Properties||convex |} The cantellated 120-cell is a uniform 4-polytope. It is named by its construction as a Cantellation operation applied to the regular 120-cell. It contains 1920 cells, including 120 rhombicosidodecahedra, 1200 triangular prisms, 600 octahedra. Its vertex figure is a wedge, with two rhombicosidodecahedra, two triangular prisms, and one octahedron meeting at each vertex. 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「Cantellated 120-cell」の詳細全文を読む スポンサード リンク
