Triakis tetrahedral altertegum

The triakis tetrahedral altertegum is a convex isochoric polychoron with 24 skew rhombic pyramids as cells. It can be obtained as the dual of the truncated tetrahedral cupoliprism.

Each cell of this polychoron has mirror symmetry, with 1 rhombus and 4 scalene triangles for faces.
