+A. Make the subalgebra class work with any subalgebra (there's nothing
+   special except a_regular_element() in there).
+
 1. Add CartesianProductEJA.
 
 2. Check the axioms in the constructor when check != False?

 5. Factor out the unit-norm basis (and operator symmetry) tests once
    all of the algebras pass.
 
-6. Refactor the current ungodly fast charpoly hack (relies on the
-   theory to ensure that the charpolys are equal.)
-
-7. If we factor out a "matrix algebra" class, then it would make sense
-   to replace the custom embedding/unembedding functions with static
-   _real_embedding() and _real_unembedding() methods.

-8. Implement random_instance() for the main EJA class.

-9. Implement random_instance() for the subalgebra class.
+6. Can we make the minimal and characteristic polynomial tests work
+   for trivial algebras, too? Then we wouldn't need the "nontrivial"
+   argument to random_eja().
