Let A A be a Hopf algebra and ⌫ be a bicovariant first order differential calculus over A A. It is known that there are three possibilities to construct a differential Hopf algebra ⌫ n s ⌫ m rJ that contains ⌫ as its first order part. Corresponding to the three choices of the ideal J, we distinguish
