I used Stella 4d to make this polyhedral compound, and this program may be tried for free at this website.
Created using Stella 4d, a program available at this website: http://www.software3d.com/Stella.php.
I made this using Stella 4d, software you can find at http://www.software3d.com/Stella.php. I also make a second version, with larger spheres and cylinders for the vertices and edges:
As it turns out, eight icosahedra form this rhombic ring, by augmentation: Measured from the centers of these icosahedra, the long and short diagonal of this rhombus are in a (√2):1 ratio. How do I know this? Because that’s the … Continue reading
