Overlaying vertex-sharing (orange) and edge-sharing (yellow) 4-fold clusters together. Both the vertex-sharing and edge-sharing 4-fold clusters have the same face plane classes and share the same relative face angles. In a way, they embeds each other. Here is an overlay of the two together to show the relationship. The edge sharing cluster is scaled to be double the edge lengths of the vertex-sharing cluster.
In this video we are rotating the structure around in Mathematica, viewing it from various angles, and changing the rotation angle as well as the transparency of the tetrahedra.
