The present invention relates to golf ball. In order to improve the indifferent character of the orientation of the ball with respect to the strike, the peripheral surface (2) of it has dimples (115,116) essentially distributed inside 2 groups of 48 elemental surfaces (113,114), identical in the same group and different from one group to the other in the form of spherical right-angle triangles, delimited by 13 equatorial circles (56 to 61, 65 to 67, 108 to 111) of the sphere defining the general shape of the peripheral surface (2) of the ball (3).
