Added assembly diagram of a new model:
Our polyhedra are of interest all over the world.
The Magic Edges sets caught the attention of a mathematics professor at the University of Berkeley (California, USA). Mr. Richard Borcherds, left a wish to complement the series with ball-shaped models with an internal structure related to the symmetry groups of the tetrahedron, octahedron, and icosahedron. And attached photos of models.
Special thanks to Mr. Richard Borcherds. It is pleasant to know that our products have received attention at a university with a century and a half history, which in 2016 took third place in the academic ranking of the best universities in the world.
New video from our partners - "ART KOSEKOMA" team, visualization of the function and its projections
According to some spiritual teachings, a polyhedron already familiar to us — a compound of two tetrahedra (stellated octahedron) — is not just a geometric form. This form is endowed with powerful energy and maybe even supernatural properties.
1. The radius of the sphere circumscribing the polyhedron;
2. The radius of the sphere inscribed in the polyhedron;
3. The surface area of the polyhedron;
4. The volume of the polyhedron.
