This post used a symbolic permutation list provided in the “rf-poytopes” Polytope Discord discussion thread to produce the Coxeter’s (cell-first, vertex-first, edge-first, and face-first) “simplified” sections shown 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) here (40 Mb). The overall convex hull of the cell-first sectioning is similar to, but not the same as, a (496-diminished form of) the H4 BiRectified 600-cell (sectioning of that is shown here).
