Abstract
Abstract A golf ball having dimples covering its surface and having six great circular paths on the surface of the golf ball where none of the paths intersect a dimple is disclosed. The six great circular paths are obtained by inscribing a cubical pattern in the surface of the golf ball, dividing each square face of the cube into four isosceles triangles by bisecting the square face twice and filling each triangle so produced with dimples. A total of twenty-four triangles are obtained on the surface of the golf ball. Golf balls having six great circles and having 360, 384, 408, and 432 dimples are disclosed.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
105 words
A golf ball having a spherical surface with a plurality of dimples formed thereon and six parting lines which do not intersect any dimple, the dimples being arranged by dividing the spherical surface into twenty-four spherical isosceles triangles, said twenty-four isosceles triangles being formed by inscribing a cube in said spherical surface and bisecting each face of said cube into four isosceles triangles, said six parting lines corresponding to six great circular paths formed along the bisecting lines of each square face of the cube, said dimples being arranged so that the dimples do not intersect the bisecting lines which form the six circular paths.
Claim 2
Dependent Claim
105 words
A golf ball having a spherical surface with a plurality of dimples formed thereon and six parting lines which do not intersect any dimple, the dimples being arranged by dividing the spherical surface into twenty-four spherical isosceles triangles, said twenty-four isosceles triangles being formed by inscribing a cube in said spherical surface and bisecting each face of said cube into four isosceles triangles, said six parting lines corresponding to six great circular paths formed along the bisecting lines of each square face of the cube, said dimples being arranged so that the dimples do not intersect the bisecting lines which form the six circular paths.
