Abstract: A golf ball is disclosed which has two poles and an equator and a modified icosahedral lattice wherein the lattice comprises five adjacent triangles on either side of the equator, with the vertices of each of the adjacent triangles being located at each of the poles and the legs of the triangles opposite said vertices being equidistantly spaced from the equator. Each triangle includes four dimples having a diameter D1 and two dimples having a diameter D2 located substantially centrally within the triangles. The remaining surface of the ball, including the remaining area within the triangles, contains dimples having a diameter D3. The diameter relationship is D1>D2>D3.
