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) = a(n-1) - a(n-4) + 2*a(n-5) - a(n-6) + a(n-9) - a(n-10) for n > 10.
G.f.: (x + 1)^2*(x^2 - x + 1)^2*(x^2 + x + 1)^2/(x^10 - x^9 + x^6 - 2*x^5 + x^4 - x + 1). (End)
