Comment (by vdelecroix):
Hi Nathann,
Because of this error, I notice that in Sage rings are not necessarily
commutative. It would hence be better have `cyclotomic_cosets` only at the
level of commutative rings... (you do not want it for the set of `2x2`
matrices over `GF(3)`).
Please review it again (it is only a cut and paste).
Vincent
