ABSTRACT:
A golf ball has dimples formed in its outer spherical surface and arranged in a geodesic pattern defined by a plurality of imaginary grid lines which divide the outer spherical surface into an icosahedron having twenty triangular regions. Each triangular region is defined by three of the grid lines which form a spherical equilateral triangle having three sides of equal length and three medians of equal length. The dimples are arranged so that each side of the triangle radially intersects at least seven dimples, and each median of the triangle radially intersects at least six dimples. The golf ball has a total of 362 dimples including 242 dimples with a diameter of 0.140 inch and 120 dimples with a diameter of 0.150 inch.
