Query: Characterisation of Meyer sets via the Freiman--Ruzsa theorem   We show that the Freiman--Ruzsa theorem, characterising finite sets with
bounded doubling, leads to an alternative proof of a characterisation of Meyer
sets, that is, relatively dense subsets of Euclidean spaces whose difference
sets are uniformly discrete.
