Let e_i denote the standard jth basis column vector, and then consider matrices whose columns are obtained by \pm e_j and permutations of these (\pm e_{s1}, ... \pm e_{sn}) <BR/>s is a permutation of 1 through n. The group of these is the "hyper-octahedral group." A hyperoctahedron is the convex hull of the union of the \pm e_j in n-space. Of course, a hypo-octahedron is a square (diamond). The n-dimensional figure has (n-1)-simplices as faces. Its 3-d faces are indeed octahedra, just as the 3-d faces of the n-simplex are terahedra.<BR/><BR/>The n-simplex has a nice projection onto the plane <BR/>as the complete graph on (n+1)-vertices that are the vertices of a regular (n+1)-gon.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-264226589944705290.post-26790033730136520142008-12-30T08:52:00.000-08:002008-12-30T08:52:00.000-08:00The obvious correction to me is to insert "analog ...The obvious correction to me is to insert "analog of a" (or "analogue" depending on your spelling preferences).
