Query: Quantum gravity on polygons and $\Bbb R\times \Bbb Z_n$ FLRW model   We fully solve the quantum geometry of $\Bbb Z_n$ as a polygon graph with
arbitrary metric lengths on the edges, finding a $*$-preserving quantum
Levi-Civita connection which is unique for $n\ne 4$. As a first application, we
numerically compute correlation functions for Euclideanised quantum gravity on
$\Bbb Z_n$ for small $n$. We then study an FLRW model on $\Bbb R\times\Bbb
Z_n$, finding the same expansion rate as for the classical flat FLRW model in
1+2 dimensions. We also look at particle creation on $\Bbb R\times \Bbb Z_n$
and find an additional $m=0$ adiabatic no particle creation expansion as well
as the particle creation spectrum for a smoothed step expansion.
