Provided is a spherical polyhedron division structure of a golf ball where dimples are arranged to have a well-defined symmetry and a dimple pattern. In the spherical polyhedron division structure, wherein an arbitrary point on a surface of a spherical body constituting a golf ball is defined as a pole, a great circle dividing the spherical body into a northern hemisphere and a southern hemisphere with respect to the pole as a reference point is defined as an equator, the surface of the spherical body is divided into six areas formed by segments connecting the pole and points obtained by dividing the equator in units of 60°, each area is divided into spherical polygons formed by four spherical rectangles and two spherical triangles having sides with different lengths, and the spherical polygons arranged in different adjacent areas are symmetric with each other.
A golf ball with a dimple pattern arranged in spherical polygons having sides with different lengths, wherein an arbitrary point on a surface of a spherical body constituting the golf ball is defined as a pole Pa, a great circle dividing the spherical body into a northern hemisphere and a southern hemisphere with respect to the pole Pa as a reference point is defined as an equator E, the surface of the spherical body is divided into six areas formed by segments connecting points E1, E3, E5, E7, E9, and E11 obtained by dividing the equator E in units of 60° and the pole Pa, each area is divided into spherical polygons formed by four spherical rectangles and two spherical triangles having different side lengths, and the spherical polygons arranged in different adjacent areas are symmetric with each other.
