{{{
sage: MS=MatrixSpace(QQ,2)
sage: A=MS([0,1,1,0])
sage: B=MS.identity_matrix()
sage: G = MatrixGroup([A,B])
sage: G
Matrix group over Rational Field with 2 generators (
[0 1] [1 0]
[1 0], [0 1]
)
sage: P = G.as_permutation_group()
sage: P
Permutation Group with generators [(), (2,3)]
}}}
One can see that the generators of the permutation group do not correspond
to those of the matrix group. They should be given in the very same order.
This is a one-line change.
