### Splitting field and mu invariant

Please inform me how to compute the following two problems

1) Splitting field of a polynomial over Z, its degree of extension over Q and it's roots.

2) The ?-invariant of other elliptic curves in an isogeny class from the ?-invariant of the minimal curve in that isogeny class.
