Index entries for signature-permutations of Catalan automorphisms

(MIT Scheme implementation of this automorphism that acts on S-expressions, i.e. list-structures:) (define (*A125982 s) (cond ((null? s) s) (else (map *A125982 (cons (except-last-pair s) (car (last-pair s)))))))

Inverse: A125981. A125984 gives the A057163-conjugate.

Sequence in context: A130960 A130927 A057162 * A125983 A130364 A130995

Adjacent sequences: A125979 A125980 A125981 * A125983 A125984 A125985
