%N Inverse of 2183rd cyclotomic polynomial.

%C Periodic with period length 2183. - _Ray Chandler_, Apr 07 2017

%F G.f. (1 + x + ... + x^36 - x^59 - ... - x^95)/(1 - x^2183) = (1 - x^37)/(1 - x)*(1 - x^59)/(1 - x^2183) = (1 + x + ... + x^36)/(1 + x^59 + x^118 + ... + x^2124) = 1/((1 - x)(1 + x^37 + x^59 +...+ x^2087)), therefore this is a linear recurrence of order 2088. - _M. F. Hasler_, Feb 16 2018
