Abstract
A golf ball having an outer spherical surface and at least 320 dimples formed in the outer surface to provide land areas on the outer surface which surround the dimples. Each of the dimples has a triangular periphery at the ball's outer surface provided by three sides and three flat surfaces which extend inwardly from the outer surface. The angle between each of the flat surfaces and a tangent to the ball's outer surface at the intersection with the flat surface is from 14.degree. to 26.degree.. Each side of each dimple extends parallel to at least a portion of the side of an adjacent dimple. The distance between the parallel sides of adjacent dimples is constant over the outer spherical surface. The total land area is no greater than 20% of a sphere which circumscribes the ball's outer spherical surface.
