COMMENTS

Needs better definition and more terms. I am having difficulty accessing this document. The complement, A', is presumably also missing from the OEIS, but we cannot be certain of that until the present sequence is extended.

It appears --as a result of the Maple program-- that a(25) in the publication is a typographical error and that the sequence is an erroneous duplicate of A026368. The associated A' sequence is A026367 - R. J. Mathar, Oct 25 2014
