FORMULA

a(n)=(1/224)*{-1571*(n mod 8)+81*[(n+1) mod 8]+221*[(n+2) mod 8]+837*[(n+3) mod 8]-619*[(n+4) mod 8]-3*[(n+5) mod 8]+137*[(n+6) mod 8]+1789*[(n+7) mod 8]}-31*[C(2*n,n) mod 2], with n>=0 [From Paolo P. Lava, Jun 03 2009]

G.f.: -(x^2-x+1)*(31*x^6+33*x^5+3*x^4-25*x^3+3*x^2+33*x+31)/((x-1)*(x+1)*(x^2+1)*(x^4+1)). [Colin Barker, Aug 11 2012]
