1. A golf ball having an outer surface comprising a plurality of dimples disposed thereon, wherein the dimples are arranged in multiple copies of a first domain and a second domain, the first domain and the second domain being tessellated to cover the outer surface of the golf ball in a uniform pattern having no great circles and consisting of four first domains and four second domains, and wherein:
the dimple pattern within the first domain is different from the dimple pattern within the second domain;
the plurality of dimples comprises dimples having at least two different diameters including a maximum dimple diameter and one or more additional dimple diameters;
each of the two or more different dimple diameters on the ball has a first domain diameter ratio defined by the equation:

 where SD1 is the number of dimples positioned within the first domain having a given diameter, and SD2 is the number of dimples positioned within the second domain having said given diameter;
SD1=SD2for the maximum dimple diameter; and
SD1≤½ (SD2)or SD1≧2(SD2)for each of the additional dimple diameters.
