Let Π be a ring property. An
additive group G is said to be an (associative) strongly Π-group if G is not nil, and
if every (associative) ring R with additive group G such that R is not a
zeroring has property Π. The (associative) strongly principal ideal groups,
and the (associative) strongly Noetherian groups are classified for groups
which are not torsion free. Some results are also obtained for the torsion free
case.
