Abstract
The present invention relates to a 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 (69) essentially distributed inside 48 identical elemental surfaces (68), in the form of spherical right-angle triangles, delimited by 9 equatorial circles (56 to 61, 65 to 67) of the sphere defining the general shape of the peripheral surface (2) of the ball (3).
