Abstract
Abstract A golf ball is provided with evenly and uniformly distributed dimples so that six great circle paths on the surface of the golf ball do not intersect any dimples. The spherical surface of the golf ball is divided into 20 identical spherical triangles corresponding to the faces of a regular icosahedron. Each of the 20 triangles is further subdivided into four smaller triangles consisting of a central triangle and three apical triangles by connecting the midpoints of each of the 20 triangles along great circle paths. The dimples are arranged so that the dimples do not intersect the sides of any of the central triangles.
