The twenty hexagons (4) with equal angles but with different sides have every other side of relatively large length A or relatively small length B in the expansion 0.10 A is less than or equal to B is less than or equal to 0.69 A with preferably B equal to 0.69 A. A long side A of a hexagon is alwasy connected to a pentagon and a short side B to another hexagon. The outer ball can also comprise six quadrilaterals (2) and eight equilateral triangles (1) of the double side length. The latter, with the aid of their side edges, have every other one fixed to a quadrilateral or to another triangle.
