Abstract
The general theory for cycling transformations in the group theoretic approach to strings is presented. It leads to a simple physical interpretation of the method which is discussed. We also demonstrate that twisting and sewing, i.e. factorization are an inevitable consequence of the method. We show that there exists a particularly simple choice of cycling transformations that leads to very great simplifications in the results for excited string scattering.
