1. A golf ball having two poles and an equator, and having a preselected number of dimples arranged in a geometrical lattice configuration based upon a modified icosahedral lattice, said lattice comprisinga first plurality of adjacent triangles on either side of the equator of the ball, with the vertices of each of the adjacent triangles being located at each pole of said ball and the legs of said adjacent triangles opposite the vertices of said triangle being equidistantly spaced a predetermined distance from the equator of said ball;

  • two adjacent rows of dimples on either side of the equator of said ball extending about said ball between said equator and said legs of said triangles opposite said vertices, said dimples in said two adjacent rows having a diameter D3;

    a first plurality of dimples lying along the lattice lines of said triangles, said first plurality of said dimples having a diameter D3;

    a second plurality of dimples lying within each of said triangles, said second plurality of dimples comprisingfour dimples having a diameter D1 greater than diameter D3;

    two dimples having a diameter D2 greater than diameter D3, but less than the diameter D1; and

    the remaining dimples lying in said triangles having a diameter D3.
