It has 9 vertices, 36 edges, 84 triangle faces, 126 tetrahedral cells, 126 5-cell 4-faces, 84 5-simplex 5-faces, 36 6-simplex 6-faces, and 9 7-simplex 7-faces. Its dihedral angle is cos−1(1/8), or approximately 82.82°. It can also be called an enneazetton, or ennea-8-tope, as a 9-facetted polytope in 8-dimensions. The name ''enneazetton'' is derived from ''ennea'' for nine facets in Greek and ''-zetta'' for having seven-dimensional facets, and ''-on''. == Coordinates == The Cartesian coordinates of the vertices of an origin-centered regular enneazetton having edge length 2 are: :$\backslash left(1/6,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash pm1\backslash right)$ :$\backslash left(1/6,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; -2\backslash sqrt,\backslash \; 0\backslash right)$ :$\backslash left(1/6,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; -\backslash sqrt,\backslash \; 0,\backslash \; 0\backslash right)$ :$\backslash left(1/6,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; -2\backslash sqrt,\backslash \; 0,\backslash \; 0,\backslash \; 0\backslash right)$ :$\backslash left(1/6,\backslash \; \backslash sqrt,\backslash \; \backslash sqrt,\backslash \; -\backslash sqrt,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0\backslash right)$ :$\backslash left(1/6,\backslash \; \backslash sqrt,\backslash \; -\backslash sqrt,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0\backslash right)$ :$\backslash left(1/6,\backslash \; -\backslash sqrt,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0\backslash right)$ :$\backslash left(-4/3,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0,\backslash \; 0\backslash right)$ More simply, the vertices of the ''8-simplex'' can be positioned in 9-space as permutations of (0,0,0,0,0,0,0,0,1). This construction is based on facets of the 9-orthoplex. 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「8-simplex」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
