Index entries for signature-permutations of Catalan automorphisms

Inverse: A130920. A122351(n) = A083927(A130919(A057123(n))). The number of cycles and the number of fixed points in range [A014137(n-1)..A014138(n-1)] of this permutation are given by A130967 and A130968. Maximum cycle sizes seems to be given by A000793 (shifted once right).

Sequence in context: A244322 A129605 A057509 * A127286 A130946 A073284
