Cofinitary groups are subgroups of the symmetric group on the natural numbers
(elements are bijections from the natural numbers to the natural numbers, and
the operation is composition) in which all elements other than the identity
have at most finitely many fixed points. We will give a motivation for the
question of which isomorphism types are possible for maximal cofinitary
groups. And explain some of the results we achieved so far.
