Comment (by chapoton):

 * Jordan algebras are not in the catalog, as far as I can see (6.7.beta4)

 * if J is a Jordan algebra, then `J in Algebras` returns False

 So I really think that the catalog 'algebras' should be kept for
 associative algebras.

 Maybe this should be discussed on sage-devel or sage-combinat-devel ?
