 4. Implement the octonion simple EJA.
 
-5. Factor out the Jordan axiom and norm tests once all of the
-   algebras pass.
+5. Factor out the unit-norm basis (and operator symmetry) tests once
+   all of the algebras pass.
 
-6. Create Element subclasses for the matrix EJAs, and then override
-   their characteristic_polynomial() method to create a new algebra
-   over the rationals (with a non-normalized basis). We can then
-   compute the charpoly quickly by passing the natural representation
-   of the given element into the new algebra and computing its charpoly
-   there. (Relies on the theory to ensure that the charpolys are equal.)

+6. The EJA random element method only returns two summands by default.
