The three boundedness classes of homeomorphism groups of countable Stone spaces are exactly the coarse equivalence classes, with the middle class quasi-isometric to the Hamming cube and infinite Hamming graphs bi-Lipschitz equivalent.

A dense subset of the Gromov boundary of the grand arc graph is identified with geodesic laminations; the graph satisfies the bounded geodesic image theorem and its boundary is non-compact.
Introduces a geometrisation framework for topological groups via left uniform and coarse structures, characterizing metrisability for Polish groups and defining minimal/maximal metrics.
Left coarse structure on G/H is not always the quotient of that on G; counterexample in mapping class groups of Loch Ness monster surfaces, plus conditions involving bounded-set liftings, transversals, and metrisability.

Gromov boundary of the Grand Arc graph
A dense subset of the Gromov boundary of the grand arc graph is identified with geodesic laminations; the graph satisfies the bounded geodesic image theorem and its boundary is non-compact.
