a(n) = 3·a(n-1) - a(n-3) for n>2, with a(0)=1, a(1)=-1, a(2)=0. A122100
Number of compositions of n when parts 1 and 2 are of two kinds. A52536
a(n) = -3·a(n-1) + a(n-3) for n>2, with a(0)=1, a(1)=1, a(2)=0. A122099
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+pi, and define a(-1)=0. Then a(n)=a(3·r+pi) gives the quantity of H9,2,0 tiles in a subdivided H9,i,r tile after linear scaling by the factor Qr, where Q=sqrt(x3-2·x) with x=2·cos(π/9). A187504
