| Nov 9, 2014 at 13:44 | comment | added | Sam Nead | Oh, that looks nice - I'll have to think about that. By the way, I sort of want to edit your answer: $Z_2 * Z_2$ is the only non-trivial free product that is two-ended (thus is virtually cyclic) while all others have infinitely many ends (so contain rank two free groups, etc). | |
| Nov 9, 2014 at 11:12 | comment | added | Anton Klyachko | @Sam, I bet your single identity forms a basis of identities of the group. (This means that all other identities are consequences of this one.) | |
| Nov 9, 2014 at 10:51 | comment | added | Sam Nead | There are several nice identities - the simplest after a few moments thought is $[x^2, y^2]$. | |
| Nov 3, 2014 at 7:46 | comment | added | Anton Klyachko | @Denis, of course not. The infinite dihedral group $Z/2Z*Z/2Z$ has elements of infinite order. | |
| Nov 3, 2014 at 7:40 | comment | added | Denis Serre | Let me try, the identity $x^2=e$ ? | |
