In seven-dimensional geometry, a cantellated 7-simplex is a convex uniform 7-polytope, being a cantellation of the regular 7-simplex. There are unique 6 degrees of cantellation for the 7-simplex, including truncations. == Cantellated 7-simplex== 3, 3, 3, 3, 3\\3\end\right\} |- |bgcolor=#e7dcc3|Coxeter-Dynkin diagram|| or |- |bgcolor=#e7dcc3|6-faces|| |- |bgcolor=#e7dcc3|5-faces|| |- |bgcolor=#e7dcc3|4-faces|| |- |bgcolor=#e7dcc3|Cells|| |- |bgcolor=#e7dcc3|Faces|| |- |bgcolor=#e7dcc3|Edges||1008 |- |bgcolor=#e7dcc3|Vertices||168 |- |bgcolor=#e7dcc3|Vertex figure||5-simplex prism |- |bgcolor=#e7dcc3|Coxeter groups||A7, () |- |bgcolor=#e7dcc3|Properties||convex |} 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 7-simplexes」の詳細全文を読む スポンサード リンク
