%N Permutation of natural numbers induced by the Catalan bijection gmA073197 acting on the parenthesizations as ordered by A014486.
%C Is there an equivalent Catalan bijection in A073200?

%o (define (gmA073197 s) (cond ((pair? s) (gmA073197 (car s)) (gmA072796! s) (gmA073197 (car s)) (gmA072797! s))) s)
%Y Inverse permutation: A073196. The car/cdr-flipped conjugate of A073208, i.e. A073197(n) = A057163(A073208(A057163(n))). Cf. also A073194-A073199.
%Y The scheme functions gma072796! and gma072797! referred to below are given in A072796 and A072797.
