Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (33, -392, 1968, -3456).
FORMULA
a(0)=1, a(1)=33, a(2)=697, a(3)=12033, a(n)=33*a(n-1)-392*a(n-2)+ 1968*a(n-3)- 3456*a(n-4) [From Harvey P. Dale, Mar 01 2012]
a(n)=(5*12^(n+3)-32*9^(n+3)+30*8^(n+3)-3*4^(n+3))/480. [Yahia Kahloune, Jun 11 2013]
