Comment (by dshurbert):
Added {{{check=True}}} as last argument for
{{{FinitelyPresentedGroupElement}}} python constructor. Adding this
argument to {{{__init__}}} for {{{FinitelyPresentedGroup}}} did not appear
to have the desired affect. The examples below now run smoothly.
{{{
sage: G = FreeGroup("a")
sage: F = G / [G([1,1,1,1,1])]
sage: F.is_abelian()
True
sage: F.order()
5
sage: [i for i in F]
[1, a, a^-1, a^2, a^-2]
sage: F([1,1,1]).inverse()
a^-3
sage: F([1,1,1]).inverse() in F
True
}}}
Is this what you meant by adding the {{{check=<bool>}}} argument? If so
then ready for review.
