%N Coordination sequence Gal.4.73.1 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_, Jan 24 2020: (Start)
%F a(n) = a(n-1) + a(n-7) - a(n-8) for n > 8.
%F G.f.: (x^8 + 3*x^7 + 6*x^6 + 6*x^5 + 4*x^4 + 6*x^3 + 6*x^2 + 3*x + 1)/(x^8 - x^7 - x + 1). (End)
