COMMENT

The signature-permutation of the automorphism which is derived from the first non-recursive automorphism *A069770 with the recursion schema RIBS (see A122200), or alternatively, derived from the seventh non-recursive automorphism *A089854 with recursion scheme SPINE or ENIPS. (see A122203, A122204 for their definitions).
