We investigate the complexity of algorithmic problems on ΓΏnitely generated subgroups of free groups. Margolis and Meakin showed how a ΓΏnite monoid Synt(H ) can be canonically and e ectively associated with such a subgroup H . We show that H is pure (that is, closed under radical) if and only if Synt
