Tetrahedral transitional biomnitruncatodecachoron

The tetrahedral transitional biomnitruncatodecachoron or tetbotid is a convex isogonal polychoron that consists of 10 orthoaligned ditruncated tetrahedra, 20 ditrigonal prisms and 30 rectangular trapezoprisms obtained as the convex hull of two opposite great prismatodecachora with A4 symmetry.

This polychoron can be alternated into a tetrahedral transitional omnisnub bidecachoron, which is also nonuniform.
