*On* the other hand, if G is *a* *torsion*-*free* abelian group with |G| =X, and G is not *free* abelian of rank &, then Ge Z. *Theorem* | states that if G is *a* solvable group of finite special rank, then Ge X. ...
It is announced in *a* postscript that the author has subsequently proved that every two-generator *one*-*relator* group with *torsion* (TOT group), which is not *a* *free* product, has only *one* NEC (cf. <x, y|x? ...
