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.
