Abstract
Abstract A golf ball having a spherical surface with a plurality of dimples being arranged with fifteen axes of symmetry. The spherical surface of the ball is divided into ten regular hexagons corresponding to the faces of a regular decahedron. Each regular hexagon is further divided into six regular triangles. Each regular triangle is subdivided into two right-angled triangles, so that all right-angled triangles from a PHC (Propellant Hexagon Configuration).
