Abstract
Golf balls have dimple patterns on their surfaces which are generated in toto from simple formulae. The dimples are arranged in rows parallel to the ball's equator. The number of dimples are based on code numbers that are multiples of four and are greater than twelve. The golf balls of the invention have markedly greater dimple symmetry than heretofore. Also one or more series of dimple patterns, as above, are disclosed whose test carry is constant for the series and in which test trajectories become flatter as the code number increases.
