Wrong Maple Program for A010892?

[Rainer Rosenthal]

In OEIS sequence A010982 there is the following Maple program:

          with(numtheory, cyclotomic);
          c := n->series(1/cyclotomic(6, x), x, 80);

I don't understand this. For each n you will get the same series.
What is this good for?
