1. A golf ball having groups of dimples on the surface thereof, whereinprovided that the ball has a phantom spherical surface (11), three first phantom orthogonal great circles (12) are drawn on the spherical surface (11) to define eight equal spherical regular triangles (13), each spherical regular triangle (13) being delimited by three sides (17) and having a center and middle points (18) on the three sides (17), and four second phantom great circles (19) are drawn on the spherical surface (11), each second phantom great circle (19) connecting the middle points (18) on two of the three sides (17) delimiting the spherical regular triangle (13), each spherical regular triangle (13) having three segments of the second phantom great circles (19);

  • a group of three dimples (14) having the same shape and an equal diameter and an equal depth is distributed about the center of each spherical regular triangle (13) such that three line segments connecting the centers of the three dimples (14) define a regular triangle (15) and the length of each line segment (DD1) of of one side of the regular triangle (15) does not exceed twice the diameter (Dm) of the dimples, and not other dimples are located within the regular triangle (15) associated with the three dimples (14),a group of two dimples (16) having the same diameter as the three dimples (14) is distributed on each side of the spherical regular triangle (13) in symmetry with respect to its middle point such that the distance (DD2) between the centers of the two dimples (16) does not exceed twice the diameter (Dm) of the dimples (16),and none of the dimples intersect the second phantom great circles (19).
