Intuitively, it may be regarded as [[Ball (association football)|footballs]] (or soccer balls) that are typically patterned with white hexagons and black pentagons. It can be found in the application of [[geodesic dome]] structures such as those whose architecture [[Buckminster Fuller]] pioneered are often based on this structure. It is an example of an [[Archimedean solid]], as well as a [[Goldberg polyhedron]].
