- Status changed from needs_work to needs_review
Most of those came from the change of what sl2
means. It also showed an inconsistency with the index set of the classical Lie algebras not being a FiniteEnumeratedSet
(well, really something having a cardinality
).

Math looks good, documentation looks good, all tests passed on my machine, and all documentation builds.
