There are a few pictures of truncated icosahedra in the article, alongside several other shapes that are not icosahedra. The point is that they have icosahedral symmetry. The L is important.
- JackFr 8mo agoI was going to comment pedantically that soccer balls were dodecahedrons not icosahedrons, but in reading the article, I came to realize that truncated icosahedrons are the same as truncated dodecahedrons. This was such a delightful realization I felt the need to comment anyway.
- zem 8mo agothat is indeed a delightful realisation! akin to when I noticed that a cube and an octahedron both had a cross section that was a regular hexagon.
- meindnoch 8mo agoHmm. I'm sorry, but truncated dodecahedra are different from truncated icosahedra. Truncated dodecahedra are made from twelve 10-gon and twenty triangular faces. Truncated icosahedra are made from twenty hexagonal and twelve pentagonal faces.
