Short answer -- no, not yet. Just out of curiosity, do you want to do this in a setting where the computation is very difficult? Or just sort of routine small computations? E.g., could you give an example of the field, etc.? > 2) Is there a function to obtain the Artin map of an Abelian > extension, or at least for the Hilbert class field of a quadratic > field? Maybe PARI (included in SAge) can do some of this. I don't think Sage itself has an easy interface to this functionality yet.
