PROGRAM

(Scheme code otherwise as for A072635, but with "transposed coordinates":)

(define A072637 (arithrank->lexrank-bijection A059906 A059905))

CROSSREFS

A072644 gives the size of the corresponding parenthesizations, i.e. A072644(n) = A029837(A014486(A072637(n))+1)/2 [A029837(n+1) gives the binary width of n].

A072637(n) = A057163(A072635(n)). Cf. also A014486, A059905, A059906, A071654, A072646.
