This polychoron is obtained from biscrox, the bistratic ike-first cap of rox, by means of the observation that the vertex figure of rox is pip. Although not all vertices could be such diminished without producing mutual intersections and without leaving the realm of CRFs, it well is possible to do so only within the medial layer and even there with pyritohedral subsymmetry only. In fact, it was obtained at the beginning of 2021 by a guy calling himself "puffer fish" by applying that diminishing at those vertices of the medial layer id which correspond to a vertex-inscribed fq-oct only.
