Description
Since they are isomorphic, we should be able to go between the two different representations:
sage: L = lie_algebras.sp(QQ, 4, representation='matrix') sage: Lp = lie_algebras.sp(QQ, 4, representation='bracket') sage: L.coerce_map_from(Lp) sage: Lp.coerce_map_from(L) sage: L(Lp.an_element()) # Boom sage: Lp(L.an_element()) # Boom
