FORMULA
cyclotomic(1573,x) is a polynomial of 120th order in the variable x^11, so it is c = 1 - x^11 - x^132 + x^264 + ... + x^1320, or with y = x^11 we can write c = 1 - y + y^11 - y^12 + y^13 - y^14 ... + y^120. - R. J. Mathar, Oct 20 2008
MAPLE
with(numtheory, cyclotomic); c := n->series(1/cyclotomic(n, x), x, 80); c(1573);
