%N Coordination sequence Gal.4.121.2 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 02 2023: (Start)
%F a(n) = 2*a(n-5) - a(n-10) for n > 11.
%F G.f.: (-2*x^11 + 3*x^10 + 4*x^9 + 8*x^8 + 14*x^7 + 20*x^6 + 16*x^5 + 16*x^4 + 14*x^3 + 6*x^2 + 4*x + 1)/(x^10 - 2*x^5 + 1). (End)
