Mathar, Oct 25 2008] a(n) = (1/30)*{19*(n mod 6)-6*[(n+1) mod 6]+39*[(n+2) mod 6]-[(n+3) mod 6]+24*[(n+4) mod 6]-21*[(n+5) mod 6]}-2*[C(2*n,n) mod 2]-8*{C[(n+1)^2,n+3] mod 2}, with n>=0. [Paolo P. Lava, Sep 24 2009] From Chai Wah Wu, Sep 21 2016: (Start) a(n) = a(n-1) - a(n-3) + a(n-4) for n > 5. G.f.: x^2*(-8*x^3 + 6*x^2 - 2*x - 5)/(x^4 - x^3 + x - 1). (End) CROSSREFS Cf. A021032.
