This excellent survey article concerns group presentations where the relators are proper powers. The most known groups with such a presentation are the so called generalized triangle groups \(\langle a,b; a^m=b^n=R^k(a,b)=1\rangle\) where \(m,n,k\geq 2\) and \(R(a,b)\) is a cyclically reduced word involving both \(a\) and \(b\). The main question of interest here is that of asking when such a group presentation with all relators proper powers is finite or infinite.
