hypercupolas consisting of 7 5-simplexes, 21 5-cell prisms and 35 Tetrahedral-Triangular duoprisms each. The vertices of the pentellated 6-simplex can be positioned...

six-dimensional geometry, a pentellated 6-cube is a convex uniform 6-polytope with 5th order truncations of the regular 6-cube. There are unique 16 degrees...

In seven-dimensional geometry, a pentellated 7-simplex is a convex uniform 7-polytope with 5th order truncations (pentellation) of the regular 7-simplex...

the pentellated 8-simplex, while the bipentellated 8-simple is doubled to [18] symmetry. The Cartesian coordinates of the vertices of the pentellated 8-simplex...
