Why is this different from A280772, which has the same name? Possibly this is an erroneous version of A280772, in which case it should be marked as "dead", but not deleted since the OEIS policy is to include published but erroneous sequences to serve as pointers to the correct versions. - N. J. A. Sloane, Jan 18 2017
