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);
