1. A golf ball having a substantially spherical surface, comprising:
a plurality of dimples disposed thereon, wherein the dimples are arranged in a pattern comprising four substantially identical dimple sections, wherein each dimple section is defined by a spherical triangle,
wherein the dimples in each of the four substantially identical dimple sections comprise at least three different dimple diameters including a minimum dimple diameter, a maximum dimple diameter, and at least one additional dimple diameter,
wherein each of the substantially identical dimple sections comprises a shared dimple having a centroid located on at least one vertex and the shared dimple located on the at least one vertex has the maximum dimple diameter, and
wherein the dimples cover about 70 percent or less of the substantially spherical surface, and wherein the pattern results in at least three dimple-free great circles on the golf ball.
