#19780: Result of matrix group morphism is not in the codomain
----------------------------+------------------------------------
Reporter: tscrim | Owner: tscrim
Type: defect | Status: new
Priority: major | Milestone: sage-7.0
Component: group theory | Keywords: group morphism

----------------------------+------------------------------------
We currently have the following:
{{{
sage: G = groups.matrix.SO(3, 3)
sage: H = groups.matrix.GL(3, 3)
sage: phi = G.hom([H(x) for x in G.gens()])
sage: phi(G.one()).parent()
Full MatrixSpace of 3 by 3 dense matrices over Finite Field of size 3
}}}
The result of the morphism should be in the codomain `H`.
