%N Number of complete triangulations of the Koch chain K_s.
%C The Koch chain K_s is a sequence of 2^s+1 points which form an xmonotone chain of unavoidable edges in the plane with the same combinatorial structure as the fractal Koch curve.
%C Given that the number of points already grows exponentially in s, the numbers of triangulations themselves have double exponential growth of roughly 9.083^(2^s), see Theorem 5 of Rutschmann, Wettstein (2022).
