%N Coordination sequence Gal.5.130.5 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 21 2019: (Start)
%F a(n) = 2*a(n-1) - a(n-2) - a(n-4) + 2*a(n-5) - a(n-6) for n > 6.
%F G.f.: (x^6 + 4*x^5 - x^4 + 2*x^3 - x^2 + 4*x + 1)/((x - 1)^2*(x^4 + 1)). (End)
