The truncated tetrahedron is an Archimedean solid. It has 4 regular hexagonal faces, 4 regular triangular faces, 12 vertices and 18 edges.

Cartesian coordinates

---

Cartesian coordinates for the vertices of a truncated tetrahedron centered at the origin are

(±3, ±1, ±1),

(±1, ±3, ±1),

(±1, ±1, ±3),

where the ± has the same parity for each coordinate, that is, all coordinates have an even number of minuses (or all have an odd number).
