View of the space lattice structure of two dodacahedrons shown from two different perspectives. The first perspective showing all the elements in the outer shell of the compound and the second perspective showing only the surface elements seen from the viewers perspective. The unseen inner platform for the dodacahedron is an icosahedron.
The following is gif of the Tri-Pent Compound. This is the base compound from which the Isocahedron and Dodecahedron are derived from. They in turn form the foundation of the Hex-Pent Compound. The radius of the Tri-Pent Compound is Tau (T) if the internodal distance of the pentagon face is unity.
