%N Coordination sequence Gal.4.25.4 where Gal.u.t.v denotes the coordination sequence for a vertex of type v in tiling number t in the Galebach list of u-uniform tilings.
%C 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.

%F Conjectures from _Chai Wah Wu_, Dec 24 2019: (Start)
%F a(n) = a(n-1) - a(n-4) + 2*a(n-5) - a(n-6) + a(n-9) - a(n-10) for n > 10.
%F G.f.: (x + 1)^2*(x^2 + x + 1)*(x^6 + x^3 + 1)/(x^10 - x^9 + x^6 - 2*x^5 + x^4 - x + 1). (End)
