Dimple patterns for golf balls

A golf ball having a plurality of dimples disposed on a spherical outer surface thereof and having a non-planar parting line, wherein:

• the plurality of dimples comprising 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 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 golf ball and two linear side edges connecting each end of the equatorial edge to a pole of the golf 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 is not rotationally symmetric about a center of the respective triangular section;
• wherein at least some dimples of the plurality of dimples have a catenary cross-sectional profile defined by x-y coordinates, wherein x=0 corresponds to a central axis of the catenary cross-sectional profile and y=0 corresponds to a minimum of the catenary cross-sectional profile, and the catenary cross-sectional profile is defined by:
