Hi Guys,

 Could you please tell me whether the invariants of quadratic forms
over \Q as defined by Conway in his Sensual Quadr form book have been
implemented in SAGE? (Or anywhere else for that matter). If not, what
has been implemented so far (for rational/integral quadratic forms)?


Thanks,

 Fernando
