This invention relates to a golf ball, in which a dimple distribution pattern is designed to secure the greatest possible number of lines of symmetry and shifting lines of symmetry on the surface of a regular spherical polyhedron based on the surfaces of a regular dodecahedron, a regular icosahedron, or a dodecaicosahedron, one of the lines 4 with the least number of intersecting dimples being used as the mold-parting line. The dimples 13 that intersect said mold-parting line are removed and equivalent dimples 33 with the aerodynamic characteristics equal to those of the dimples that are removed may be arranged in a symmetrical manner with respect to the line 4 in their place. <IMAGE> |
