 OFFSET 0,1 COMMENTS Periodic with period length 1573. - Ray Chandler, Apr 07 2017 LINKS Ray Chandler, Table of n, a(n) for n = 0..2000 FORMULA Maple says that 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.
