COMMENT
|
Sequence terms for n>12 are conjectured. A conjectured continuation of the sequence starting with n=21 would be: 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 In the visualization given at the link the shortest edges are those drawn as golden color rods.
