This is a scaliform edge-faceting of a Grünbaumian double-cover of the small rhombated tesseract (srit). The additional 48 octagons are inscribed into the former small rhombicuboctahedra (sirco), the additional 128 triangles are used to produce a quadruple coincidence of a tetrahedral subset of the so far only doubled up octahedra (oct).
