Let v(0) be the column vector (1,0,0,0)'; for n>0, let v(n) = [1 1 1 1 / 1 1 1 0 / 1 1 0 0/ 1 0 0 0] v(n-1). Sequence gives third entry of v(n). A91024

Let i be in {1,2,3,4} and let r >= 0 be an integer. Let p = {p₁, p₂, p₃, p₄} = {-1,0,1,2}, n=3·r+p_i, and define a(-1)=1. Then a(n)=a(3·r+p_i) gives the quantity of H_9,1,0 tiles in a subdivided H_9,i,r tile after linear scaling by the factor Q^r, where Q=sqrt(x³-2·x) with x=2·cos(π/9). A187503
