Hello,
I really do not like
sage: M = MatrixSpace(QQ,3)
sage: G = SL(3, QQ)
sage: m1 = M(1)
sage: m2 = G(1)
sage: m1
[1 0 0]
[0 1 0]
[0 0 1]
sage: m2
[1 0 0]
[0 1 0]
[0 0 1]
sage: m1 == m2
False
Shouldn't it be True? One way would be to have a coerce embeddig from G
to M which looks natural to me. Is it?
Best,
Vincent
