Hexagonal double prismantiprismoid

The hexagonal double prismantiprismoid is a convex isogonal polychoron and the fifth member of the double prismantiprismoid family. It consists of 24 hexagonal antiprisms, 24 hexagonal prisms, 72 rectangular trapezoprisms, 288 isosceles trapezoidal pyramids, 72 tetragonal disphenoids, and 144 digonal disphenoids. 1 hexagonal antiprism, 1 hexagonal prism, 2 rectangular trapezoprisms, 5 isosceles trapezoidal pyramids, 1 tetragonal disphenoid, and 2 digonal disphenoids join at each vertex. It can be obtained as the convex hull of two orthogonal hexagonal-dodecagonal prismantiprismoids. However, it cannot be made scaliform.
