COMMENT

Periodic with length 9^2=81.

FORMULA

a(n)=(1+floor(n/9)) mod 9.

a(n)=1+floor(n/9)-9*floor((n+9)/81).

a(n)=(((n+9) mod 81)-(n mod 9))/9.

a(n)=((n+9-(n mod 9))/9) mod 9.

G.f. g(x)=(1-x^9)(1+2x^9+3x^18+4x^27+5x^36+6x^45+7x^56+8x^63)/((1-x)(1-x^81)).

G.f. g(x)=(1-x^9)*sum{0<=k<8, (k+1)*x^(9*k)}/((1-x)(1-x^81)).

G.f. g(x)=(8x^81-9x^72+1)/((1-x)(1-x^9)(1-x^81)).
