  • Coxeter Regular Polytopes &sec;7.6 (p.131 of the Dover edition) says: "...obvious fact that the symmetry group of the one-dimensional polytope {} has order N0=2."
  • In the top table, I'd number the columns the other way around: tk has a vertex, not a cell, at the center of the k-dimensional element.

  • I replaced prism notation as t{2,p} - used and justified in the 1954 paper, and I'm satisfied it is better, even if {2,p}, a dihedral polyhedron, is degenerate for 3-space.
  • On "numbering" columns (0,1,2,3 point subscripts), you may be right, at least I have to think! Feel free to change this table in Schläfli_symbol#Extended_for_uniform_polychora_and_3-space_honeycombs as you believe correct.
