1. In a golf ball characterized by enhanced flight distance and enhanced aerodynamic symmetry, the ball having a generally spherical surface with dimple pattern thereon, the improvement comprising:

  • a) between about 75% and 85% of the ball spherical surface occupied by the dimples,b) there being dimples of at least two different diameters, all of which have diameters within the range of 0.110 to 0.160 inches,c) there being multiple dimple intersecting segments or arcs of great circles on the ball surface, which define six-sided spherical surface hexagons associated with axially opposite polar zones,d) and there being 24 of the smaller dimples within each of said hexagons,e) the smaller dimples within each said hexagon grouped in clusters symmetrically spaced about an axis of said ball centrally intersecting said hexagons,f) the ball also having an equator, and certain of said segments or arcs of great circles also defining multiple spherical surface triangles with legs on said equator, and legs coincident with said sides of said hexagon,g) and wherein there are six of said clusters equally spaced about said axis, in each hexagon, each said cluster comprising four dimples.
