ABSTRACT:
The present invention provides a golf ball of improved symmetry by regulating volume, area, edge length and array symmetry indexes Vi, Si, Li, and Ni obtained from coordinates (.theta.j, .phi.j) of a dimple center as represented by the latitude (in radian) and longitude of the ball and a radius rj and a volume vj of a dimple, for correcting a difference in dimple effect caused by a distortion of roundness of the ball. The golf ball does not have dimples which intersect the mold parting line, and the dimples occupy at least 65% of the ball surface.
