 The Dymaxion Fuller map projection is a icosahedron polyhedral projection that intends

 In comparison to the Snyder's Icosahedral Equal Area, this projection relies on a specific way

 was first invented by Buckminster Fuller in 1943 using a cubostahedron as basis.
 The idea to use an icosahedron came later in 1954, and it wasn't until 1978 that the projection 
 was formally mathematically defined :cite:`Gray1995`.
