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
