Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 0, 0, 536, 0, 0, 0, 0, 0, 0, 1).
FORMULA
G.f.: -(x^13 -20*x^12 +21*x^11 -41*x^10 +62*x^9 -103*x^8 +165*x^7 +268*x^6 +165*x^5 +103*x^4 +62*x^3 +41*x^2 +21*x +20) / (x^14 +536*x^7 -1). - Colin Barker, Nov 25 2013
