 1. Add references and start citing them.
 
-2. Pre-cache charpoly for some more algebras.
+2. Profile (and fix?) any remaining slow operations.
 
-3. Profile the construction of "large" matrix algebras (like the
-   15-dimensional QuaternionHermitianAlgebra(3)) to find out why
-   they're so slow.
+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. What the ever-loving fuck is this shit?
+4. Add dimension bounds on any tests over AA that compute element
+   subalgebras.
