ABSTRACT:
A golf ball includes a substantially spherical surface containing a plurality of dimples of differing diameter. Twelve spherical regular pentagons and twenty spherical regular triangles are arranged on the spherical surface in a manner corresponding to a dodecaicosahedron (12-20 hedron). Each pentagon shares a same asymmetrical dimple pattern such that each of five sides of each pentagon have a dimple pattern that differs from a dimple pattern on four other sides, and all of the pentagons share the same five differing side patterns. Six great circle paths are arranged about the spherical surface, each great circle path being bounded on one side by a series of five adjacent pentagons, one of which is a reference pentagon, and the other four of which are respectively and angularly displaced at angles of 72.degree., 288.degree., 144.degree. and 216.degree. with respect to the reference pentagon. A sequence of angular pentagon displacement of the series is consistent along all six great circle paths.
