Eight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C 60 buckminsterfullerene, e) C 540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube. Carbon is capable of forming many allotropes due to its valency.Well-known forms of carbon include diamond and graphite. In recent decades many more allotropes and forms of carbon have been discovered and researched including ball shapes such as buckminsterfullerene and sheets such as graphene.ight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C 60 buckminsterfullerene, e) C 540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube.

Vickers acquired the company in 1980 and sold it to Volkswagen in 1998.
Mini became a marque in its own right in 1969. In the 1980s, British Leyland was broken-up and in 1988 Rover Group, including Mini, was acquired by British Aerospace. In 1994, Rover Group was acquired by BMW. In 2000, Rover Group was broken up by BMW, with BMW retaining the Mini brand.
