Truncated icosahedron - Wikipedia
In geometry, the truncated icosahedron is a polyhedron that can be constructed by truncating all of the regular icosahedron's vertices. Intuitively, it may be regarded as footballs (or soccer balls) that are typically patterned with white hexagons and black pentagons. It can be found in the application of geodesic dome … See more
The truncated icosahedron can be constructed from a regular icosahedron by cutting off all of its vertices, known as truncation. … See more
The balls used in association football and team handball are perhaps the best-known example of a spherical polyhedron analog to the truncated icosahedron, found in everyday life. The … See more
