Golf ball with polar region uninterrupted dimples

In a golf ball characterized by enhanced flight distance and enhanced aerodynamic symmetry, the ball having a generally spherical surface with patterns of dimples thereon, the improvement comprising:

• a) the ball having a main axis and opposite surface polar regions associated with said axis,
• b) there being six geodesic lines defining a spherical hexagon bordering each said polar region, said axis being at the center of said hexagons,
• c) there being at least three groups of dimples associated with each said hexagon, all of the dimples of said groups being completely within said spherical hexagon,
• d) the dimples of each group having the same diameter, the dimples of one group having diameters d.sub.1, the dimples of the second group having diameters d.sub.2, and the dimples of the third group having diameters d.sub.3, and
• e) the dimples of each group arranged symmetrically about said axis, said geodesic lines also intersect to form six like isosceles spherical triangles respectively adjacent the six sides of each said hexagon, there being additional dimples confined by said triangles, all dimples confined by each triangle being completely within each triangle, each said geodesic line having a length between said opposite ends which is at least 20% of its surface circumference of the golf ball, said golf ball having an equational region everywhere spaced from said spherical hexagons, the ball having dimple density per unit area at said equatorial region which is greater than dimple density per unit area in said spherical hexagons.
