Comment (by tscrim):
I would get rid of the `copy` attribute, instead make this a
`UniqueRepresentation` (or perhaps a `UniqueFactory` so we can better
control the cache key), and make the table a tuple of immutable matrices
that gets set by the `__classcall_private__`.
We also need to fix the category, which is wrong for non-associative, non-
unital cases.
