Tétrahémihexaèdre

In Geometry, the tétrahémihexaèdre is a Polyèdre not-convex uniform, indexed under the name U4.

It has 6 tops and 12 edges, the length of which it has 4 triangular faces, are divided with the regular Octaèdre.

It is only the polyhedral not-prismatic uniform with an odd number of face. It is single like only the polyhedral uniform with a Caractéristique of Euler equal to 1 and is consequently a representation of the Plan projective reality very similar to the Roman Surface.

The " part; hemi" name means that some faces pass through the center of the polyhedron, in this case of the square faces.
