FORMULA
| a(n) = A106833(n) mod 9.
G.f.: -(3+4*x+8*x^3+6*x^4+3*x^5+3*x^6+7*x^7+2*x^9+6*x^10+6*x^11+3*x^12+x^13+5*x^15+6*x^16) / ((x-1) * (1+x+x^2) * (1+x^3+x^6) * (1+x) * (1-x+x^2) * (1-x^3+x^6)).
a(n)=(1/306)*{-44*(n mod 18)+109*[(n+1) mod 18]-10*[(n+2) mod 18]-78*[(n+3)
mod 18]+24*[(n+4) mod 18]+41*[(n+5) mod 18]+58*[(n+6) mod 18]+7*[(n+7)
mod 18]-61*[(n+8) mod 18]-27*[(n+9) mod 18]+126*[(n+10) mod 18]-61*[(n+11)
mod 18]+7*[(n+12) mod 18]+58*[(n+13) mod 18]+41*[(n+14) mod 18]-129*[(n+15)
mod 18]+75*[(n+16) mod 18]-10*[(n+17) mod 18]}, with n>=0 [From Paolo P. Lava (paoloplava(AT)gmail.com), Mar 27 2009]
