## Abstract

A golf ball is provided with a dimple pattern comprising two substantially identical elongated dimple pattern elements which fit together to form the complete dimple pattern. The dimple pattern can contain 344 dimples covering about 70.4% of the golf ball surface or 392 dimples covering about 73.3%, or other combinations of dimple count and coverage. The sizes of the dimples can be varied among either four distinct dimple sizes ranging from about 0.14 inches to about 0.17 inches or eight distinct dimple sizes ranging from about 0.11 inches to about 0.175 inches, or other dimple size combinations. The arrangement of dimples on the golf ball can be divided into a plurality of triangles having identical dimple arrangements with bilateral symmetry.

## Claims

### Claim 1

A golf ball dimple pattern comprising:
two substantially identical elongated elements capable of fitting together to form the complete dimple pattern; and
a plurality of dimples disposed in each one of the elongated elements, wherein the plurality of dimples forms an identical dimple pattern in each elongated element;
wherein the plurality of dimples are capable of being divided into eight triangles, four of the eight triangles being disposed in each of two hemispheres of the golf ball; each triangle comprising a single line of symmetry, and, for a given hemisphere, the line of symmetry associated with one or more of the four triangles varies orientation with respect to a common point where one of the vertices of each one of the four triangles meet; each triangle comprising a single dimple of a smallest size, the smallest sized dimple disposed adjacent one of the vertices of the triangle; and each triangle comprising an identical arrangement of dimples; and
wherein the plurality of dimples comprises 392 total dimples comprising eight different dimple diameters ranging from 0.11 inches to about 0.175 inches.
