Triangular antitegum

The trigonal antitegum, also known as the trigonal trapezohedron, is an antitegum based on a triangle. If all edges are equal length, the result is the regular cube. The general triangular antitegum has 6 identical rhombic faces.

Variants of the triangular antitegum exist that are dual to the triangular antipodium as well, using 2 different sets of 3 kites for faces.
