Abstract
The disclosure relates to a dimple arrangement of a golf ball in which 10 to 25 dimples of at least two different diameters are arranged in 24 congruent spherical triangles, respectively consisting of two equal sides and divided by the ridge lines of a complete 24-hedron so that the dimple arrangements in the 24 congruent spherical triangles are identical to each other, and one of the great circle paths formed by connecting the ridge lines with each other coincides with a parting line formed by a pair of hemispherical molds.
