1. The tetrahedral prism is bounded by two tetrahedra and four triangular prisms . 2. A "'rhombicosahedron "'shares its vertex arrangement with the 20 triangular prisms . 3. The triangular faces of the triangular prisms are joined to the truncated tetrahedra. 4. Then the four side-facets of the prism, the triangular prisms become tridiminished icosahedra. 5. The vertex figure is a triangular prism , containing two cubes and three cuboctahedra. 6. The Mendel's shape resembles a triangular prism rather than a cube. 7. It is formed as two parallel heptagonal antiprisms connected by cubes and triangular prisms . 8. It shares its vertex arrangement with the 20 triangular prisms . 9. It results from composing the two enantiomorphs of the compound of 10 triangular prisms . 10. It is formed as two parallel hexagonal antiprisms connected by cubes and triangular prisms .
