%N Backwards van Eck transform of A010060.
%C See A171898 for definition. This assumes the offset of A010060 is taken to be 1.
%C A161916 gives the forwards van Eck transform of A010060.
%C Since A001285(n) = 1+A010060(n) differ only by a constant, this is also the Backwards van Eck Transform of A001285. - _R. J. Mathar_, Jun 24 2021
