%N Coordination sequence Gal.4.70.2 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_, Feb 28 2022: (Start)
%F a(n) = 2*a(n-1) - 2*a(n-2) + 2*a(n-3) - 3*a(n-4) + 4*a(n-5) - 3*a(n-6) + 2*a(n-7) - 2*a(n-8) + 2*a(n-9) - a(n-10) for n > 10.
%F G.f.: (x^5 + x^4 + x^2 + x + 1)*(x^5 + x^4 + x^3 + x + 1)/((x - 1)^2*(x^4 + 1)*(x^2 - x + 1)*(x^2 + x + 1)). (End)
