We show under MA(Οƒ -centered) the existence of at least (2 Ο‰ ) + non-homeomorphic topological group topologies on the free Abelian group of size 2 Ο‰ which make it countably compact and separable. In particular, under GCH the maximum possible number of such topologies is attained. As a corollary, we
