"Your Graduation" No. 6 helped me create a 3d model of the 14th form of the icosahedron. I did not stop there ...
Look at the photo. This is the only one of its kind model of a polyhedron made of concrete - the Fourteenth stellated form of an icosahedron. The description of the model is in the book of Magnus Wenninger. The diameter of my model is 1330 mm. "
And at the moment, I am engaged in the manufacture of the Szilassi polyhedron.
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.
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.
