Dimple patterns for golf balls

A golf ball having a dimple pattern disposed on a substantially spherical phantom surface, the phantom surface having a radius that is equal at all points along the circumference of the golf ball, wherein the dimple pattern comprises:

• a plurality of dimples arranged in a pentagonal dipyramid pattern, the pentagonal dipyramid pattern consisting of ten substantially identical dimple sections, wherein each dimple section is defined by a spherical triangle having three vertices,
• wherein the dimples in each of the substantially identical dimple sections have a corresponding dimple diameter and a corresponding edge angle,
• wherein the dimples in each of the substantially identical dimple sections comprise:
• (i) at least three different dimple diameters including a minimum dimple diameter equivalent to the smallest dimple diameter within the dimple section, a maximum dimple diameter, and at least one additional dimple diameter, wherein each of the at least three different dimple diameters range from about 0.030 inches to about 0.200 inches, and
• (ii) substantially identical edge angles,
• wherein each of the substantially identical dimple sections comprises a dimple located on at least one vertex and the dimple located on the at least one vertex has the minimum dimple diameter, and
• wherein the dimples cover less than 70 percent of the substantially spherical phantom surface.

• wherein the dimples in each of the substantially identical dimple sections have a corresponding dimple diameter and a corresponding edge angle,
• wherein the dimples in each of the substantially identical dimple sections comprise five or more different dimple diameters including a minimum dimple diameter equivalent to the smallest dimple diameter within the dimple section, a maximum dimple diameter, and at least three additional dimple diameters, wherein each of the five or more different dimple diameters range from about 0.030 inches to about 0.180 inches and differ by more than 0.005 inches,
• wherein each of the substantially identical dimple sections comprises a dimple located on at least one vertex and the dimple located on the at least one vertex has the minimum dimple diameter, and
• wherein the dimples cover less than 70 percent of the substantially spherical phantom surface and the pattern results in one dimple free great circle on the golf ball.
