The golf ball having a spherical surface with a number of dimples formed in it. The spherical surface comprises eight spherical triangles delineated by three great circle parting lines not intersecting any dimples, the parting lines being formed by projecting the edges of an inscribed regular octahedron onto the spherical surface, each of the triangles having dimples located within such parting lines. The division of each triangle by three division lines angularly spaced at 120 degrees from one another and originating at the centre of each triangle forms three spherical quadrilaterals each having identical dimple patterns. Each of the patterns is not bilaterally symmetrical across any apex line extending from the centre of the triangle to an apex of the triangle. |
