 OFFSET 0,3 COMMENTS Is there an equivalent Catalan bijection in A073200? LINKS A. Karttunen, Gatomorphisms (with the complete Scheme source) PROG (Scheme function implementing this automorphism on list-structures:) (define (gmA073196 s) (cond ((pair? s) (gmA072797! s) (gmA073196 (car s)) (gmA072796! s) (gmA073196 (car s)))) s) CROSSREFS Inverse permutation: A073197.
