Comment:
Hello,
I created a branch from the ticket with `sage -dev`. The review can starts
from there.
What's the point of the following code in `_element_constructor_`?
{{{
if hasattr(P, '_freegroup_'):
if P.FreeGroup() is self:
return self.element_class(self, x.Tietze(), **kwds)
}}}
As far as I looked, there is no object in Sage with a `_freegroup_`
attribute.
Vincent
