A dimpled configuration for a golf ball wherein the dimples are arranged in a modified icosahedral lattice comprising a first set of five adjacent triangles on either side of the equator of the ball, with the vertices of each of the triangles being located at each pole of the ball and the sides opposite the polar vertices being spaced a distance from the equator of the ball. A second set of five triangles smaller than the first set of triangles equally spaced between the first set of triangles and the equator of the ball, each of the second set of triangles having a vertex common with adjacent ones of the first set of triangles, with the leg opposite the common vertex being parallel to but spaced from the equator. A first plurality of dimples having a diameter D1 lying along the lattice forming the first and second set of triangles, and a second plurality of dimples having a diameter D2 within the lattice of the first and second set of triangles and between the lattice of the second set of triangles, D1 being greater than D2, with a dimple-free line about the equator of the ball. |
