Index entries for linear recurrences with constant coefficients, signature (6118,-1970319,33501524,-1970319,6118,-1).
FORMULA
G.f.: -((25*(-19057-23405799*z-130714666*z^2+9631442*z^3-30549*z^4+5*z^5))/((1-5778*z+z^2)*(1-322*z+z^2)*(1-18*z+z^2))).
a(n) = 6118*a(n-1) - 1970319*a(n-2) + 33501524*a(n-3) - 1970319*a(n-4) + 6118*a(n-5) - a(n-6).
