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-2) + a(n-3) + a(n-7) - a(n-8) + a(n-9) - a(n-10) for n > 14.
G.f.: (-x^14 + 2*x^10 + 3*x^9 + 7*x^8 + 8*x^7 + 10*x^6 + 9*x^5 + 9*x^4 + 8*x^3 + 6*x^2 + 3*x + 1)/(x^10 - x^9 + x^8 - x^7 - x^3 + x^2 - x + 1). (End)
