Web22 dec. 2024 · Explanation: Buckminsterfullerene is a type of fullerene with the formula C60. It has a cage-like fused-ring structure (truncated icosahedron) that resembles a soccer ball, made of twenty hexagons and twelve pentagons, with a carbon atom which has one π bond and two σ bonds at each corner of the shape to create a universal vertex. WebAll in all we have a polyhedral partition of S 2 with the exterior of the rectangle as an extra facet. By Euler's formula we have. (1) e + 2 = v + f + 1 . The edges can be counted in two ways: (2) 2 e = 6 f + v b , since every edge belongs to two hexagons or one hexagon and the extra facet, and. (3) 2 e ≥ 3 ( v − 4) + 2 ⋅ 4 = 3 v − 4 ,
