Triangular double antiprismoid

The triangular double antiprismoid is a convex isogonal polychoron that consists of 12 triangular antiprisms, 36 tetragonal disphenoids and 72 sphenoids obtained as the convex hull of two orthogonal 3-3 duoantiprisms. However, it cannot be made uniform.

The triangular double antiprismoid can be vertex-inscribed into a tetradisphenoidal diacosioctacontoctachoron.
