+3. Implement the octonion simple EJA. We don't actually need octonions

4. Pre-cache charpoly for some small algebras?
15-dimensional QuaternionHermitianAlgebra(3)) to find out why
they're so slow.
-6. We should compute whether or not the algebra is associative if it
- is unknown. I guess the "associative" argument should be ternary
- (True, False, None)? We should also figure out the correct
- True/False values for the example classes, and of course add an
- _is_associative() method.
+6. Instead of storing a basis multiplication matrix, just make
+ product_on_basis() a cached method and manually cache its
+ entries. The cython cached method lookup should be faster than a
+ python-based matrix lookup anyway.
-7. When field=RDF, subalgebra construction is failing because the
- inner product isn't associative? Actually, it's the combination
- of field=RDF and orthonormalize=True.
