Abstract
We show that every maximal group in the smallest ideal of (βN,+) contains c2 discrete copies of (Z,+) the closures of any two of which intersect only at the identity. We also show that the same conclusion applies to copies of the free group on two generators (and consequently the free group on countably many generators).
