A277807 lists the "sporadic" solutions to A048720(n, A065621(n)) = k^2, i.e., those solutions where n is not in A023758 (not yet proved: these are precisely those solutions where k <> n). This sequence gives the corresponding values of k.
If n is included in this sequence, then also 2n is included (and vice versa), thus the sequence is infinite and wholly determined by its odd terms.
