We show that it is consistent with ZFC + Β¬CH that there is a maximal almost disjoint permutation family A β Sym(N) such that A is a proper subset of an eventually different family E β N N and |A| < |E|. We also ask several questions in this area.

Recall that S or Sym β«ήβ¬ is the topological group consisting of all Ο± w x permutations of β«ήβ¬ equipped with the natural topology. In Ca Cameron defines an element of S to be cofinitary if it fixes only finitely many Ο± elements of β«,ήβ¬ a subgroup of S to be cofinitary if all its elements other Ο± than
Let D be a division ring (possibly commutative) and V an infinite-dimensional left vector space over D. We consider irreducible subgroups G of GL(VJ containing an element whose fixedpoint set in V is non-zero but finite dimensional (over D). We then derive conclusions about cofinitary groups, an ele
