%N Coordination sequence Gal.4.19.3 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-2) + a(n-3) + a(n-5) - a(n-6) + a(n-7) - a(n-8) for n > 11.
%F G.f.: (-2*x^11 + x^8 + 7*x^7 + 5*x^6 + 7*x^5 + 10*x^4 + 5*x^3 + 5*x^2 + 3*x + 1)/((x - 1)^2*(x^2 + 1)*(x^4 + x^3 + x^2 + x + 1)). (End)
