An aerodynamically symmetrical golf ball is provided including a patterned outer surface having 492 dimples arranged in twenty triangles based upon an inscribed modified icosahedron lattice on the surface of the ball. As a result of the modification of the lattice, a predetermined spacing exists between two in-line rows of dimples on opposite sides of an equatorial line about said ball, the spacing being created by the modification of th icosahedron on the surface of the ball.

An aerodynamically symmetrical golf ball having two poles and an equator and having a preselected number of dimples arranged in a twenty triangular configuration based upon a modified icosahedron lattice, said lattice comprising a plurality of adjacent triangles on either side of the equator with one vertice of each of said adjacent triangles being located at each pole of said ball; all vertices other than the said polar vertices being displaced from their standard icosahedral location a predetermined distance towards the nearest pole, each of said vertices being interconnected by a constant radius arc on the surface of said ball; the center point of each of said constant radius arcs which are substantially parallel to said equator being moved towards the equator a predetermined distance, said center points and adjacent vertices lying on a constant radius curve; said preselected number of dimples being spaced within said modified lattice such that the dimples adjacent to and on opposite sides of said equator are substantially in-line and spaced a predetermined distance apart so as to provide a dimple-free equator.
