Vincenzo Librandi, Table of n, a(n) for n = 0..1000
Index entries for linear recurrences with constant coefficients, signature (0,0,1).
FORMULA
G.f.: 3*x^2/(1 - x^3). - Chai Wah Wu, Jun 21 2016
From Wesley Ivan Hurt, Jul 02 2016: (Start)
a(n) = a(n-3) for n>2.
a(n) = 1 - cos(2*n*Pi/3) - sqrt(3)*sin(2*n*Pi/3).
a(n) = 3*(1 - sgn((n+1) mod 3)).
a(n) = 1 + (n mod 3) - ((n+1) mod 3). (End)
