Abstract
Abstract A golf ball having dimples covering its surface and having seven great circular paths on the surface of the golf ball where none of the paths intersect a dimple is disclosed. The seven great circular paths are obtained by laying out a cuboctahedron on the surface of the golf ball, dividing each of the six square faces of the cuboctahedron into four isosceles triangles by bisecting each square twice. The dimples are arranged by filling each triangle with dimples. A cuboctahedron is a fourteen-sided figure with eight triangular faces and six square faces. Bisecting the square faces twice provides a total of 32 triangles per cuboctahedron. Golf balls having seven great circular paths and 360, 384 and 408 dimples are disclosed.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
126 words
A golf ball having a spherical surface with a plurality of dimples formed thereon, and seven parting lines which do not intersect any dimple, the dimples being arranged by dividing the spherical surface into twenty-four isosceles triangles and eight equilateral triangles, said twenty-four isosceles triangles and eight equilateral triangles being formed by inscribing a cuboctahedron in said spherical surface and bisecting each square face on said cuboctahedron into four isosceles triangles, four of said seven parting lines corresponding to the edges of said cuboctahedron and the remaining three of said seven parting lines corresponding to the square faces' bisecting lines, said dimples being arranged in said twenty four isosceles triangles and said eight equilateral triangles such that the dimples do not intersect the seven parting lines.
Claim 2
Dependent Claim
126 words
A golf ball having a spherical surface with a plurality of dimples formed thereon, and seven parting lines which do not intersect any dimple, the dimples being arranged by dividing the spherical surface into twenty-four isosceles triangles and eight equilateral triangles, said twenty-four isosceles triangles and eight equilateral triangles being formed by inscribing a cuboctahedron in said spherical surface and bisecting each square face on said cuboctahedron into four isosceles triangles, four of said seven parting lines corresponding to the edges of said cuboctahedron and the remaining three of said seven parting lines corresponding to the square faces' bisecting lines, said dimples being arranged in said twenty four isosceles triangles and said eight equilateral triangles such that the dimples do not intersect the seven parting lines.
