In eight-dimensional geometry , a stericated 8-simplex is a convex uniform 8-polytope with 4th order truncations (sterication ) of the regular 8-simplex . There are 16 unique sterications for the 8-simplex including permutations of truncation, cantellation, and runcination.
Stericated 8-simplex
Coordinates The Cartesian coordinates of the vertices of the stericated 8-simplex can be most simply positioned in 9-space as permutations of (0,0,0,0,1,1,1,1,2). This construction is based on facets of the stericated 9-orthoplex .
