Compound of eight triangular prisms

Compound of eight triangular prisms
Type	Uniform compound
Index	UC31
Polyhedra	8 triangular prisms
Faces	16 triangles, 24 squares
Edges	72
Vertices	48
Symmetry group	octahedral (Oh)
Subgroup restricting to one constituent	3-fold dihedral (D3)

This uniform polyhedron compound is a symmetric arrangement of 8 triangular prisms, aligned in pairs with the axes of three-fold rotational symmetry of an octahedron. It results from composing the two enantiomorphs of the compound of 4 triangular prisms.
