text: Icosahedrons are the most symmetrical of all polyhedrons, it is the most symmetrical system for the subdivision of a spherical surface into modular units and all spherical biologic structures must be icosahedrons to be stable or propped up by the adjacent structure so that, together, they create a stable structure,(fractals?), like bubbles in a foam.
