COMMENTS

Each row of this table has length 10 and corresponds to one term of A100909. n = 0 is normally represented as the single digit 0, so the first row here is 1, 0, 0, 0, 0, 0, 0, 0, 0, 0.

FORMULA

From Robert Israel, Jul 08 2016: (Start)

a(n,k) = a(A059995(n),k) + (1 if A010879(n)=k, otherwise 0).

G.f. g(x,y) satisfies g(x,y) = ((1-x^10)/(1-x))*g(x^10,y) + (x^10-x)/(1-x) + x^10/(1-x^10) + x*y*(1-x^9*y^9)/((1-x^10)*(1-x*y)). (End)

MAPLE

PROG
