%N Number of reduced words of length n in Coxeter group on 26 generators S_i with relations (S_i)^2 = (S_i S_j)^3 = I.
%C The initial terms coincide with those of A170745, although the two sequences are eventually different.
%C Computed with MAGMA using commands similar to those used to compute A154638.
%H <a href="/index/Rec#order_03">Index entries for linear recurrences with constant coefficients</a>, signature (24, 24, -300).
%F G.f.: (t^3 + 2*t^2 + 2*t + 1)/(300*t^3 - 24*t^2 - 24*t + 1)
