Dimple patterns for golf balls

A golf ball having a plurality of dimples disposed on the spherical outer surface thereof, wherein:

• the plurality of dimples comprises at least three different dimple diameters, including a minimum dimple diameter, a maximum dimple diameter, and at least one additional dimple diameter;
• the golf ball consists of two hemispheres separated by an equator, the two hemispheres having substantially identical dimple arrangements;
• each hemispherical dimple arrangement consists of four triangular sections that are defined by projecting the four faces of a square pyramid onto the hemisphere such that each of the four triangular sections is defined by a border consisting of a linear equatorial edge which corresponds to a portion of the equator of the ball and two linear side edges connecting each end of the equatorial edge to a pole of the ball;
• the four triangular sections of each hemisphere are substantially identical in size and dimple arrangement;
• the dimple arrangement within each of the four triangular sections optionally includes a shared polar dimple having a centroid that lies at the vertex of the two side edges of the section;
• the dimple arrangement within each of the four triangular sections is not rotationally symmetric about the center of the section;
• each of the four triangular sections can be divided into a polar region from latitude angle 0° to latitude angle 30°, an intermediate region from latitude angle 30° to latitude angle 60°, and an equatorial region from latitude angle 60° to latitude angle 90°, where latitude angle 0° is the pole and latitude angle 90° is the equator;
• each of the polar region, the intermediate region, and the equatorial region includes at least one dimple having the maximum dimple diameter;
• the polar region has a dimple surface coverage Sp, the intermediate region has a dimple surface coverage Si, the equatorial region has a dimple surface coverage Se, and Si<Sp<Se.
