FORMULA

a(n) = (1/98)*(-163*(n mod 14) - 2*((n+1) mod 14) + 5*((n+2) mod 14) + 5*((n+3) mod 14) + 19*((n+4) mod 14) + 19*((n+5) mod 14) + 61*((n+6) mod 14) - 51*((n+7) mod 14) - 9*((n+8) mod 14) - 9*((n+9) mod 14) + 5*((n+10) mod 14) + 5*((n+11) mod 14) + 12*((n+12) mod 14) + 173*((n+13) mod 14)) - 13*(C(2*n,n) mod 2), with n >= 0. - Paolo P.
