From the introduction: When \(H\) is a subgroup of a group \(G\) then the natural way to combine \(H\) and \(G\) is to write \(G=AH\) where \(A\) is a left transversal to \(H\) in \(G\). In this survey we shall consider the situation that \(G=AH=BH\) and the left transversals \(A\) and \(B\) are connected by the commutator condition \([A,B]\leq H\). We investigate the solubility of \(G\) as well as the situation in some finite simple groups. The situation and the conditions that we study arise in a natural way from some problems in loop theory and quasigroup theory.For the entire collection see [Zbl 0839.00022].
