This polyhedron with 32 faces has 60 vertices (corners) and 90 edges. One easily verifies Euler's formula for polyhedra (see Leonhard Euler): 32 + 60 = 90 + 2.
It is a model for the Buckminsterfullerene (C_{60}) molecule. The diameter of the football and this buckyball are 22 cm and ca. 1 nm, respectively, hence the size ratio is 200,000,000 : 1.
Other designs for footballs exist, mainly being made up of curved strips of leather. There are also indoor footballs, which are made of one or two pieces of plastic. Often these have designs printed on them to resemble a traditional leather ball.
