Abstract
In this short note, we characterise some Gorenstein versions of the concept of a group being of type as introduced by Olympia Talelli. And, we also generalize a different Talelli result regarding the coincidence of the classical and the Gorenstein cohomological dimension of torsion-free groups in Kropholler's class.
