Abstract
Abstract A golf ball having dimples covering its surface, and having three great circular paths on the surface of the golf ball where none of the paths intersect a dimple is disclosed. The three great circular paths are obtained by laying out a truncated octahedron on the surface of the golf ball and dividing the six square faces into four equal isosceles triangles. The great circular paths are coextensive with the bisecting lines. Golf balls having 368 and 632 dimples and having three great circles are disclosed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
123 words
A golf ball having a spherical surface with a plurality of dimples formed thereon, and three parting lines which do not intersect any dimples, the dimples being arranged by dividing the spherical surface into eight hexagons and twenty-four isosceles triangles, the eight hexagons and twenty-four isosceles triangles being formed by inscribing a truncated octahedron in said spherical surface, said eight hexagons corresponding to the eight hexagons of the truncated octahedron, the twenty-four isosceles triangles corresponding to the twenty-four isosceles triangles formed by bisecting the six square faces of the truncated cuboctahedron; said three parting lines corresponding to the bisecting lines of the six square faces; said dimples being arranged in said twenty-four isosceles triangles so that they do not intersect any parting line.
Claim 2
Dependent Claim
123 words
A golf ball having a spherical surface with a plurality of dimples formed thereon, and three parting lines which do not intersect any dimples, the dimples being arranged by dividing the spherical surface into eight hexagons and twenty-four isosceles triangles, the eight hexagons and twenty-four isosceles triangles being formed by inscribing a truncated octahedron in said spherical surface, said eight hexagons corresponding to the eight hexagons of the truncated octahedron, the twenty-four isosceles triangles corresponding to the twenty-four isosceles triangles formed by bisecting the six square faces of the truncated cuboctahedron; said three parting lines corresponding to the bisecting lines of the six square faces; said dimples being arranged in said twenty-four isosceles triangles so that they do not intersect any parting line.

Claim 8
Dependent Claim
96 words
A golf ball having a spherical surface with a plurality of dimples thereon and three great circular paths which do not intersect any dimples, the circular paths being arranged on the spherical surface by inscribing a truncated octahedron in said spherical surface, and bisecting the square faces of said truncated octahedron twice to form twenty-four isosceles triangles; the great circular paths corresponding to the bisecting lines of each square face; the dimples being arranged in said isosceles triangles and in the hexagonal faces of said truncated octahedron so that they do not intersect the bisecting lines.
Claim 9
Dependent Claim
96 words
A golf ball having a spherical surface with a plurality of dimples thereon and three great circular paths which do not intersect any dimples, the circular paths being arranged on the spherical surface by inscribing a truncated octahedron in said spherical surface, and bisecting the square faces of said truncated octahedron twice to form twenty-four isosceles triangles; the great circular paths corresponding to the bisecting lines of each square face; the dimples being arranged in said isosceles triangles and in the hexagonal faces of said truncated octahedron so that they do not intersect the bisecting lines.
