A177766 and the similar sequences that use odd powers in diophantine
equations should clearly state whether terms with negative s are
counted, or whether they do not contribute for some reason in case of which the
comment should indicate that the inclusion/avoidance of negative s
in the definition is irrelevant to the terms, or perhaps just use |s|
(absolute values) in the definition.
