WebTammes problem (33, 34). As illustrated in Figure 2, when covering a sphere with three spherical caps, each center of the cap is located on the vertices of an equilateral triangle touching the sphere, giving the maximum coverage density D(N) of 75%. WebTammes Problem: Other N The Tammes problem has been solved exactly for only 3 N 14 and N = 24. It was solved for N = {5,7,8,9} by Schutte and van der Waerden¨ in 1951, N = {10,11} by Danzer in his 1963 Habilitationsschrift. The case N = 24 was solved by Robinson in 1961 showing the configuration of centers were the vertices of a snub cube.
