The lace city display shows that this polychoron well is monostratic (in sloping direction), but also can be considered bistratic (in given orientation). Dissecting this non-orbiform polychoron accordingly would not only cut the gybef (at the left slope) into 2 trips, but the whole polychoron gets splitted into segmentochoric components: into trip || refl ortho trip (upper stratos) and tepe (lower one). That cutting plane there shows up a trip pseudo facet. In fact, the other way round, this polychoron well can be considered as an external blend of those 2 components.

It is obvious from the above lace city display as well as from its name that the 2 left trip cells, one of either stratos, here are corealmic and thus combine into that gybef. But it is also true that the trips marked * in the below incidence matrix are corealmic, and thus likewise could be replaced by a single rhombic prism instead (60-120-60-120 degrees rhombs), thereby erasing also the joining square, which also is marked * below. Further the squippies marked † become corealmic with the tets as well, then possibly being replaced by a sheered digonal cupola where the lacing squares become the same rhomb types. The thus here omitted joining triangle accordingly is also marked † below. – Neither of those possible descriptions qualifies as CRF, as either the convexity is violated (pairs of incident coplanar faces) or otherwise the existance of rhombs.
