I've generated all permutations for the 10 gon ring, and i've got the following 16 digit maximum :
9, 4, 1; 10, 1, 3; 6, 3, 5; 7, 5, 2; 8, 2, 4. The sum is 14.
Why is this solution wrong? Any idea whats wrong with my gon ring?

Please see the attached picture.

"Working clockwise, and starting from the group of three with the numerically lowest external node" means
your gon-ring would produce the following answer:
6,3,5;7;5;2.....
as you should strart with the lowest number i.e. 6
But then there is a "higher" solution.
