At the first glance this CRF just looks as it would be a mere bistratic stack of segmentochora. But here the squippies of the upper segment happen to become corealmic with the cubes of the lower. Thus in here they blend into esquipies instead. In fact, these happen to be parts in turn of the esquidpies of poxic, from which this polychoron just is the vertex-first bistratic cap.

The Stott expansion of this polychoron is biscsrico.
