Square scalene

The square pyramidal pyramid, or squasc, is a CRF segmentochoron (designated K-4.4 on Richard Klitzing's list). It consists of a square pyramid connected to another square pyramid and four triangular pyramids, which meet at an external point.

It can be viewed as a quarter of the hexadecachoron or a half of the octahedral pyramid.
