Index entries for linear recurrences with constant coefficients, signature (1,1,-1,-1,1,1,-1,-1,1,1,-1).
FORMULA
O.g.f.: x*(x^8+8x^7+4x^6+5x^4+4x^2+2x+1)/((x-1)^2*(1+x)*(x^2+x+1)*(x^2-x+1)*(x^4-x^2+1)). - R. J. Mathar, Jul 04 2008
a(n) = a(n-1) + a(n-2) - a(n-3) - a(n-4) + a(n-5) + a(n-6) - a(n-7) - a(n-8) + a(n-9) + a(n-10) - a(n-11) for n > 10. - Chai Wah Wu, Jan 09 2021
