Hexagonal double prismantiprismoid

The hexagonal double prismantiprismoid is a convex isogonal polychoron and the fifth member of the double prismantiprismoids that consists of 24 hexagonal antiprisms, 24 hexagonal prisms, 72 rectangular trapezoprisms, 288 isosceles trapezoidal pyramids, 72 tetragonal disphenoids and 144 digonal disphenoids obtained as the convex hull of two orthogonal bialternatosnub hexagonal-ddoecagonal duoprisms. However, it cannot be made scaliform.
