"Das oberste Ausstellungsgeschoss ist aufwendiger gestaltet: das dreiecksförmige Grundraster der Decken ist als Kassettendecke mit Tetraedern ausgebildet, die eine zusätzliche Dreidimensionalität schaffen."

tetrahedrons
Explanation:
As space-fillers, tetrahedra cannot pack together. They will instead insist on twisting into a "tetrahelix" -- a helical structure made of tetrahedrons which expands in either direction. The same could be said for the octahedron if you tried to stack one atop another. In addition, if you truncate each of the four points of a tetrahedron, you will have a beautiful octahedra laying on its side in the middle. But if you pack tetrahedrons and octahedrons together, you can fill space with ease. The presence of 60-degree angles within a lattice of tetrahedrons and octahedrons gives the final structure an inherent cross-bracing in all directions.
