%N Coordination sequence Gal.5.252.3 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_, Apr 13 2024: (Start)
%F a(n) = 2*a(n-4) - a(n-8) for n > 16.
%F G.f.: (-2*x^16 - 2*x^14 + x^11 + x^9 + 4*x^8 + 8*x^7 + 11*x^6 + 16*x^5 + 15*x^4 + 13*x^3 + 7*x^2 + 5*x + 1)/(x^8 - 2*x^4 + 1). (End)
