OEIS Sequences

Random walks (binomial transform of A006054). A5021

Expansion of (1-x)/(1-x-2·x²+x³). A52547

Number of walks of length n on P₃ plus a loop at the end. A96976

Let i be in {1,2,3} and let r >= 0 be an integer. Let p = {p₁, p₂, p₃} = {-2,0,1}, n=2·r+p_i, and define a(-2)=1. Then, a(n)=a(2·r+p_i) gives the quantity of H_7,1,0 tiles in a subdivided H_7,i,r tile after linear scaling by the factor x^r, where x=sqrt(2·cos(π/7)). A187065

a(n) = a(n-1) + a(n-2) if n is even and a(n) = a(n-3) + a(n-4) if n is odd, with a(0) = a(1) = a(2) = 0 and a(3) = 1. A265755
