Abstract
A golf ball has dimples arranged in eight spherical equilateral triangles obtained by projecting, on the imaginary spherical surface of the golf ball, the ridge lines of a regular octahedron inscribing the imaginary spherical surface. Three great circles corresponding to the ridge lines being projected on the spherical surface. One great circle coinciding with a mold seam is formed as the sole great circle unintersecting dimples and the other two great circles intersect dimples. Between 300 to 550 dimples are formed in the golf ball with the dimples being equivalently arranged in each of the eight spherical equilateral triangles.
