A hyperoctahedron
A "symmetric" representation of a hyperoctahedron, that is one of the six regular polytopes in dimension 4. The hyperoctahedron has 8 vertices, 16 faces of dimension 3, which are tetrahedra (here, 8 of the type of the figure on the left and 8 similar to the figure in the centre); the vertex figures are octahedra (on the right).
