%N Coordination sequence Gal.6.72.4 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 24 2019: (Start)
%F a(n) = a(n-5) + a(n-9) - a(n-14) for n > 15.
%F G.f.: (-2*x^15 + 3*x^14 + 4*x^13 + 10*x^12 + 12*x^11 + 20*x^10 + 19*x^9 + 22*x^8 + 21*x^7 + 23*x^6 + 18*x^5 + 18*x^4 + 11*x^3 + 8*x^2 + 4*x + 1)/(x^14 - x^9 - x^5 + 1). (End)
