A hyperoctahedron
A Schlegel diagram 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. The figure in the centre puts in evidence the fact that the hyperoctahedron is a bipyramid on an octahedron; the image on the right shows the vertex figures (which are octahedra).
