# quasiisomorphic groups and torsion [closed]

Are there two finitely generated quasiisomorphic groups $G$ and $H$ such that $G$ is torsionfree and $H$ has torsion elements of arbitrarily large order?

Out of curiosity, what does it mean for two groups to be quasiisomorphic? –  S. Carnahan Nov 30 '13 at 12:45
I guess quasiisomorphic should be quasiisometric, right? –  Benoît Kloeckner Nov 30 '13 at 13:29
There is a notion of quasi-isomorphic groups but I would bet OP did not mean it. –  Misha Nov 30 '13 at 15:55
The groups to check would be Tarski monsters with infinite central normal subgroup: is the extension class bounded or not. In the former case you get an example. –  Misha Nov 30 '13 at 17:11
What is a bounded group? –  Igor Belegradek Nov 30 '13 at 21:18
