-1. Add CartesianProductEJA.
+1. Add references and start citing them.
 
-2. Add references and start citing them.
+2. Profile (and fix?) any remaining slow operations.
 
-3. Implement the octonion simple EJA.
+3. When we take a Cartesian product involving a trivial algebra, we
+   could easily cache the identity and charpoly coefficients using
+   the nontrivial factor. On the other hand, it's nice that we can
+   test out some alternate code paths...
 
-4. Factor out the unit-norm basis (and operator symmetry) tests once
-   all of the algebras pass.
-
-5. Override inner_product(), _max_test_case_size(), et cetera in
-   DirectSumEJA.
-
-6. Switch to QQ in *all* algebras for _charpoly_coefficients().
-
-7. Pass already_echelonized (default: False) and echelon_basis
-   (default: None) into the subalgebra constructor. The value of
-   already_echelonized can be passed to V.span_of_basis() to save
-   some time, and usinf e.g. FreeModule_submodule_with_basis_field
-   we may somehow be able to pass the echelon basis straight in to
-   save time.
+4. Add dimension bounds on any tests over AA that compute element
+   subalgebras.
