Table of n, a(n) for n=0..98.

FORMULA

a(n) = (1/30)*{(n mod 6)+16*[(n+1) mod 6]-19*[(n+2) mod 6]+11*[(n+3) mod 6]-4*[(n+4) mod 6]+31*[(n+5) mod 6]}-5*[C(2*n,n) mod 2], with n>=0. [Paolo P. Lava, Nov 11 2009]

From Chai Wah Wu, Jun 21 2016: (Start)

a(n) = a(n-1) - a(n-3) + a(n-4) for n > 4.

G.f.: x^2*(2 - x + 5*x^2)/(1 - x + x^3 - x^4). (End)
