Golf balls have dimple patterns on their surfaces 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. 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. As shown in Fig. 1 at the polar region three dimples 18 are located in the ultimate circle 'U' and nine dimples 19 are located in the penultimate circle 'P'. <IMAGE> |
