A number of attractive 20-compounds of the regular
tetrahedron can be constructed.

The compound illustrated above are implemented in the Wolfram Language as `PolyhedronData`[`"TetrahedronTwentyCompound"`,
1].

These tetrahedron 20-compounds are illustrated above together with their duals
and common midspheres.

The common solids and convex hulls are illustrated
above.
