%N Permutation of natural numbers induced by the Catalan bijection gmA073208 acting on the parenthesizations as ordered by A014486.

%C Is there an equivalent Catalan bijection in A073200?

%o (Scheme function implementing this automorphism on list-structures:)

%o (define (gmA073208 s) (cond ((pair? s) (gmA073208 (cdr s)) (gmA072797! s) (gmA073208 (cdr s)) (gmA072796! s))) s)

%Y Inverse permutation: A073207. The car/cdr-flipped conjugate of A073197, i.e. A073208(n) = A057163(A073197(A057163(n))). Cf. also A073205-A073210.

%Y The scheme functions gma072796! and gma072797! referred to below are given in A072796 and A072797.
