I stumbled across this compound the other day, while playing around with Stella 4d: Polyhedron Navigator (available here).
At first, I thought this was a compound of six tetrahedra, but careful examination reveals that the tetrahedra are missing parts along the middle of some of their edges. I looked up the canonical compound of six tetrahedra in Stella‘s library, and here it is. As you can see, it’s quite similar — but it does have those “missing” pieces added.
I made this compound using Stella 4d, which you can try for free at this website.

Stella 4d: Polyhedron Navigator has a “put models on vertices” function which I used to build this complex of tetrahedra. If you’d like to try this software for yourself, there is a free trial version available at http://www.software3d.com/Stella.php.
This is the compound of two tetrahedra, also known as Johannes Kepler’s Stella Octangula.
I found the five variations of this polyhedral compound shown below, located deep within the stellation-series of the great rhombicuboctahedron.

This compound has three parts: two tetrahedra, plus one smaller cube. I made it using Stella 4d: Polyhedron Navigator, which you can try for free at http://www.software3d.com/Stella.php.
This can also be called the compound of two truncated tetrahedra.
