Abstract
A method of laying out a dimple pattern on a golf ball comprises constructing a geodesically expanded icosahedron having 60 equal triangular faces. Each of the 60 triangular faces includes a substantially identical dimple pattern. The geodesic icosahedron is formed by constructing an icosahedron which is circumscribed by a sphere which has the diameter of the golf ball. A point is determined in each of the 20 icosahedral triangles of the icosahedron by bisecting the three sides of the icosahedral triangle. A geodesic focus point is determined by projecting said point onto the surface of the sphere. Each geodesic focus point is connected to each apex of the icosahedral triangle so that each geodesic focus point forms a right regular tetrahedron having a base formed by the icosahedral triangle and three triangular faces which merge at the geodesic focus point.
