Is there an equivalent Catalan bijection in A073200?

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

(define (gmA073210 s) (cond ((pair? s) (gmA073210 (car s)) (gmA072797! s) (gmA073210 (car s)) (gmA072796! s))) s)

Inverse permutation: A073209. The car/cdr-flipped conjugate of A073199, i.e. A073210(n) = A057163(A073199(A057163(n))). Cf. also A073205-A073208.

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

Sequence in context: A013944 A123497 A123501 * A073196 A086430 A073194

Adjacent sequences: A073207 A073208 A073209 * A073211 A073212 A073213
