By the way, one has to be careful using some of the methods of U. In
particular,
sage: u1=U.list_of_elements_of_multiplicative_group()
sage: u==u1
True
but
sage: type(u[0])
< type 'sage.rings.integer_mod.IntegerMod_int' >
type(u1[0])
< type 'int' >
and using u1 instead of u would produce a different result.
