%N Coordination sequence Gal.4.123.1 where G.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_, Jan 24 2020: (Start)

%F a(n) = 2*a(n-5) - a(n-10) for n > 10.

%F G.f.: (x^2 + x + 1)^2*(x^6 + 2*x^5 + 3*x^4 + 2*x^3 + 3*x^2 + 2*x + 1)/(x^10 - 2*x^5 + 1). (End)
