Abstract
A golf ball having at least three different sizes of dimples and whose total dimple area quotient is optimized for increasing the golf ball's flying distance. The dimple area quotient represents the sum of the surface area indexes of all dimples divided by the surface area of the ball. The golf ball contains a plurality of dimples disposed about the spherical surface of the golf ball, and said plurality of dimples includes at least three types of dimples, said plurality of dimples having a total dimple surface area quotient Dst of at least 4, wherein the total dimple surface area quotient Dst is defined as: ##EQU1## wherein n is a positive integer of at least 3, k is one of plurality of discrete dimple groups covering the spherical surface of said golf ball,
