Digonal gyrobicupolic ring (EntityTopic, 17)
From Hi.gher. Space
K4.8 is the first as-yet-unclassified convex segmentochoron. Its cells are 1 tetrahedron, 4 square pyramids and 2 triangular prisms. Its faces are 1+4 squares and 4+4+4 triangles. It has 2+4+4+8 edges and 4+4 vertices.
Keiji studied it explicitly to try to understand more about the segmentochora.

It is possible to construct K4.8 from three different pairs of polytopes:
