Finitely generated free-by-(finite cyclic) groups turn out to be distinguished from each other by their finite quotients - and this is thanks to being very constrained by their finite subgroups and their centralisers. This has a consequence to distinguishing in the same way the free-by-cyclic groups with centre. This is joint work with Martin Bridson.
