In geometry, a truncated tesseract is a uniform 4-polytope formed as the truncation of the regular tesseract. There are three truncations, including a bitruncation, and a tritruncation, which creates the ''truncated 16-cell''. == Truncated tesseract== 24 |- |bgcolor=#e7dcc3|Edges |colspan=2|128 |- |bgcolor=#e7dcc3|Vertices |colspan=2|64 |- |bgcolor=#e7dcc3|Vertex figure |colspan=2| Isosceles triangular pyramid |- |bgcolor=#e7dcc3|Dual |colspan=2|Tetrakis 16-cell |- |bgcolor=#e7dcc3|Symmetry group |colspan=2|BC4, (), order 384 |- |bgcolor=#e7dcc3|Properties |colspan=2|convex |- |bgcolor=#e7dcc3|Uniform index |colspan=2|''12'' 13 ''14'' |} The truncated tesseract is bounded by 24 cells: 8 truncated cubes, and 16 tetrahedra. 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 tesseract」の詳細全文を読む スポンサード リンク
