Note that there may be other vertices in the Galebach list of u-uniform tilings with u <= 6 that have this same coordination sequence. See the Galebach link for the complete list of A-numbers for all these tilings.

FORMULA
|
a(n) = 2*a(n-1) - 2*a(n-2) + 2*a(n-3) - 2*a(n-4) + 2*a(n-5) - a(n-6) for n > 6.
G.f.: (x^6 + 4*x^5 + x^4 + 4*x^3 + x^2 + 4*x + 1)/((x - 1)^2*(x^2 - x + 1)*(x^2 + x + 1)). (End)
