5. Profile the construction of "large" matrix algebras (like the
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.
-
-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.
