ABSTRACT:
Golf ball2has numerous dimples8. The surface of the golf ball is divided by comparting lines CM corresponds to edges of a regular icosahedron into eight first spherical regular triangles T1, six second spherical regular triangles T2, and six third spherical regular triangles T3. The first spherical regular triangles T1do not include the equatorial line EQ. The second spherical regular triangles T2and the third spherical regular triangles T3include the equatorial line EQ. The dimple pattern on the first spherical regular triangle T1is different from the dimple patterns on the second spherical regular triangle T2and third spherical regular triangle T3. The dimple pattern on the first spherical regular triangle T1has rotational symmetry and line symmetry. The dimple pattern on the second spherical regular triangle T2and the third spherical regular triangle T3has neither a rotational symmetry nor line symmetry. This golf ball2does not have any great circle path.
