Vincenzo Librandi, Table of n, a(n) for n = 0..1000

FORMULA

a(n) = (1/338)*(21*(n mod 13)-5*((n+1) mod 13)-109*((n+2) mod 13)+255*((n+3) mod 13)-109*((n+4) mod 13)+125*((n+5) mod 13)-57*((n+6) mod 13)-31*((n+7) mod 13)+125*((n+8) mod 13)+21*((n+9) mod 13)-83*((n+10) mod 13)-57*((n+11) mod 13)+177*((n+12) mod 13))-6*(C(2*n,n) mod 2). [Paolo P. Lava, Oct 27 2009]

G.f.: x^2*(6*x^11 + 6*x^10 + 5*x^9 + 9*x^7 + 4*x^6 + 8*x^5 + 5*x^4 + 3*x^3 + 7*x^2 + 7*x + 3)/(1 - x^13). - Chai Wah Wu, Jun 21 2016
