 OFFSET 0,4 COMMENTS Row n is the signature permutation of the Catalan automorphism which is obtained from the n-th automorphism in the table A122201 with the recursion scheme "FORK", or equivalently row n is obtained as FORK(FORK(n-th row of A089840)). See A122201 for the description of FORK. Each row occurs only once in this table. Inverses of these permutations can be found in table A122290. REFERENCES A. Karttunen, paper in preparation, draft available by e-mail. LINKS CROSSREFS The known rows of this table: row 0 (identity permutation): A001477, row 1: A122351, row 2: A122363.
