This invention is about a golf ball formed a number of dimple on its surface which are arranged uniformly and definitely and which have two vertical symmetric axis. The golf ball consists of a solid sphere having an equator(1E or 2E) or two largest circumferences in which any dimple does not cross, the dimple divides the surface of ball into four equal globular equiangular triangles corresponding to the triangle of globular regular tetrahedron, the equator of golf ball is consisted with the side sharing with two triangles, the other two triangles of regular tetrahedron are divided into two equal parts respectively, the first equator is angled by turning the globular triangle, in angling the second equator perpendicular to the first equator or the largest circumference, the second equator is consisted with the side sharing with the other two triangles of tetrahedron, two triangles not divided by the first equator are divided into two equal parts to compose eight equal globular triangles, the dimple is arranged in eight triangles, any dimple does not cross each side of triangle. |
