FORMULA

Period length 12: a(n)=a(n-12).

a(n) = A154811(n+6) = A155110(n) (mod 9).

a(n)=(1/33)*{18*(n mod 12)+40*[(n+1) mod 12]+84*[(n+2) mod 12]-4*[(n+3) mod 12]+84*[(n+4) mod 12]+40*[(n+5) mod 12]+18*[(n+6) mod 12]-4*[(n+7) mod 12]-48*[(n+8) mod 12]+40*[(n+9) mod 12]-48*[(n+10) mod 12]-4*[(n+11) mod 12]}, with n>=0 [From Paolo P. Lava (ppl(AT)spl.at), Feb 13 2009]
