ABSTRACT:
A ball for ball games, organized in 18 squares and adjusted by 8 helices, wherein the ideal sphericity is obtained when the distance from the center (Y) to the corners of the triangle in the center of the helix is equal to the difference in distance that exists between the square and its diagonal: If c=sqrt(3)*(d−a) and d=⅛C, then sphere.
