adding the tag [congugacy-classes].

Improved the formulation of the question, and assigned a more specific tag.

| Nov 3, 2013 at 11:12 | comment | added | Alain Valette | A nice exercise in a first course in group theory, is to show that a finite group with 2 conjugacy classes, is the 2-element group... | |
| Nov 3, 2013 at 11:01 | comment | added | Stefan Kohl♦ | If one additionally requires the group to be finitely generated, the question is Problem 9.10 in the Kourovka Notebook, and has been answered in: D. V. Osin, Small Cancellations over Relatively Hyperbolic Groups and Embedding Theorems, Ann Math. 172, no. 1 (2010), 1-39, annals.math.princeton.edu/2010/172-1/p01, ArXiV link: arxiv.org/abs/math/0411039. | |
| Nov 3, 2013 at 10:41 | comment | added | Anton Klyachko | @Gerry, I do not think this is a homework. An example can be easily constructed using iterated HNN-extensions. A finitely generated example also exists but this is a highly non-trivial result of D. Osin. | |
