OEIS Sequences

a(n) = a(n-1) + 2·a(n-2) - a(n-3), with a(0) = a(1) = 0, a(2) = 1. A6053
Number of (s(0), s(1), ..., s(2n)) such that 0 < s(i) < 7 and |s(i) - s(i-1)| = 1 for i = 1,2,...,2·n, s(0) = 1, s(2n) = 3. A94790
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+pi, and define a(-2)=0. Then, a(n)=a(2·r+pi) gives the quantity of H7,2,0 tiles in a subdivided H7,i,r tile after linear scaling by the factor xr, where x=sqrt(2·cos(π/7)). A187066
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+pi, and define a(-2)=1. Then, a(n)=a(2·r+pi) gives the quantity of H7,1,0 tiles in a subdivided H7,i,r tile after linear scaling by the factor xr, where x=sqrt(2·cos(π/7)). A187065
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 + pi and define a(-2)=0. Then, a(n) = a(2·r + pi) gives the quantity of H7,3,0 tiles in a subdivided H7,i,r tile after linear scaling by the factor xr, where x = sqrt(2·cos(π/7)). A187067
