Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 0, 0, 0, 1).

FORMULA

a(n) = (1/32)*(-87*(n mod 8) + 5*((n+1) mod 8) + 5*((n+2) mod 8) + 21*((n+3) mod 8) - 11*((n+4) mod 8) + 5*((n+5) mod 8) + 5*((n+6) mod 8) + 97*((n+7) mod 8)) - 12*(C(2*n,n) mod 2), with n >= 0. - Paolo P. Lava, Jul 28 2009
