Bicrystallodecachoron

The bicrystallodecachoron is a convex isochoric polychoron with 40 laterotruncated triangular pyramids as cells. It can be obtained as the dual of the biprismatodecachoron.

Each cell of this polychoron has triangular pyramidal symmetry, with a ditrigonal base, 3 pentagons, and 3 triangles for faces.
