Old description:
> Apparently the Magma interface can't do this yet. See #11455 for
> examples. If I understand it correctly, this requires adding code for
> {{{FldNumElt}}} to {{{data/extcode/magma/sage/basic.m}}}.
New description:
Apply:
* [attachment:trac_11456_sage.patch] to the main Sage source
* [attachment:trac_11456_extcode.patch] to data/extcode
This adds the following conversion functionality.
From Magma to Sage:
* Absolute and relative number fields in one or more generators
(previously not possible).
* Elements of absolute and relative number fields in one generator
(previously not possible).
From Sage to Magma:
* Relative number fields (previously only absolute number fields).
Converting relative number field elements from Sage to Magma is more
difficult (because of garbage collection) and is left for a later patch.
