A080866 Number of equal shortest edges in the solutions of the Tammes' problem. 1

%I #10 Jul 12 2017 07:57:35

%S 1,3,6,6,12,12,16,18,19,25,30,24,28

%N Number of equal shortest edges in the solutions of the Tammes' problem.

%C A conjectured continuation of the sequence starting with n=15 would be: 30 32 34 34 34 39 40 42 43 60 48 46 52 52 54 63 60 66 66 68 66 72 66 72 76 78 81 85 82 88 84 91 89 120 96 102.

%C In the visualization given at the link the shortest edges are those drawn as golden color rods.

%D See under A080865.
