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 (123,124,125,126) essentially distributed inside 126 elemental surfaces (104,105,106,115), delimited by 12 equatorial circles (92 to 103) of the sphere defining the general shape of the peripheral surface (2) of the ball (3), on the basis of: PA1 6 identical elemental surfaces (104) of spherical, regular octagonal form, PA1 48 identical elemental surfaces (105) of spherical triangular form, PA1 3 groups of 24 identical elemental surfaces (106,231,115) of spherical quadrilateral form having two equal opposite angles (107,108,131,116,117) and two different opposite angles (109,110,133,134,118,119) defined by two respective equal length sides (111,112,113,114,135, 136,137,138,120,121,122,123).
