 | Tetrahemihexahedron |
- Vertex description: 3.4.3/2.4
- Faces: 7
- Edges: 12
- Vertices: 6
- External facelets: 16
- Dual: Tetrahemihexacron (infinite)
- Name breakdown:
- Tetra-: 4 faces (triangles) lie parallel to those of a
tetrahedron
- -hemi-hexa-: Hemi = through the centre of model. Hexa = faces
parallel to a cube, but only half as many (3)
because they're hemi.
Other than some prisms, this is the only uniform polyhedron with an odd
number of faces. It has seven: 4 triangles (yellow) and 3 squares (red). The
squares intersect each other, bisecting each other along their diagonals.
Every part of each square is visible, from one side or the other.
It is a faceted octahedron (that is it shares the
same vertex positions).
