We now determine the relationship between the coefficients of Ri and Qi arising from σ(g) and σ(gs), where i is fixed by the choice of generator s. The coefficient of (t+li)−1 in Qi is given by a complicated sum, and we construct a separate automato…

Higher rank lamplighter groups are graph automatic

We show that the higher rank lamplighter groups, or Diestel-Leader groups $\Gamma_d(q)$ for $d \geq 3$, are graph automatic. This introduces a new fa…
