This post used the symbolic permutation list provided in the “rf-poytopes” Polytope Discord discussion thread to produce the Coxeter (cell-first, vertex-first, edge-first, and face-first) sections for it (below).

You can navigate the matrices of links below or simply download the ZIP files for the SVG sectioning for Jonathan Kirk’s Convex Regular Face (CRF) which is a 496-diminished form of the H4 BiRectified 600-cell here (40 Mb).
