Bitruncatodecachoron

The bitruncatodecachoron is a convex isogonal polychoron that consists of 10 tetrahedra, 20 triangular antiprisms and 30 tetragonal disphenoids obtained as the convex hull of two opposite truncated pentachora.

Vertex coordinates
Coordinates for a bitruncatodecachoron, created from two truncated pentachora of edge length 1, are given by:
