Compound of four tetrahedra

In geometry, a compound of three tetrahedra can be constructed by three tetrahedra in a number of different symmetry positions.

One compound can be constructed rotating a tetrahedron by 45 degree turns along an axis of the middle of an edge. It has dihedral symmetry, D₄
