Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

COMMENTS

An involution of nonnegative integers.

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).
