In five-dimensional geometry, a truncated 5-simplex is a convex uniform 5-polytope, being a truncation of the regular 5-simplex. There are unique 2 degrees of truncation. Vertices of the truncation 5-simplex are located as pairs on the edge of the 5-simplex. Vertices of the bitruncation 5-simplex are located on the triangular faces of the 5-simplex. == Truncated 5-simplex == 6 t |- |bgcolor=#e7dcc3|Cells |45 |30 15 t |- |bgcolor=#e7dcc3|Faces |80 |60 20 |- |bgcolor=#e7dcc3|Edges |colspan=2|75 |- |bgcolor=#e7dcc3|Vertices |colspan=2|30 |- |bgcolor=#e7dcc3|Vertex figure |colspan=2|100px Tetra.pyr |- |bgcolor=#e7dcc3|Coxeter group |colspan=2| A5 (), order 720 |- |bgcolor=#e7dcc3|Properties |colspan=2|convex |} The truncated 5-simplex has 30 vertices, 75 edges, 80 triangular faces, 45 cells (15 tetrahedral, and 30 truncated tetrahedron), and 12 4-faces (6 5-cell and 6 truncated 5-cells). 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「Truncated 5-simplexes」の詳細全文を読む スポンサード リンク
