The octahedron is slightly more complex than the tetrahedron. The square pyramids built by the Egyptian Pharaohs are each half an octahedron. The octahedron is one of the five Plato solids. Plato ascribed the element of air to this shape. There are 11 ways  (nets) to fold an octahedron from two-dimensional nets. The octafold building unit is one of these nets.
