%N Row 1 of A122289 and A122290. An involution of nonnegative integers.
%C The signature-permutation of the automorphism which is derived from the automorphism *A057163 with the recursion schema FORK (see A122201), that is, from the first non-recursive automorphism *A069770 with FORK(FORK(*A069770)) or equivalently, with KROF(KROF(*A069770)) (see A122202).
