When doing some computations with algebraic numbers, a pari error appears.
Example:
```
sage: R.=QQbar[]
sage: f=x^7-x^3+5*x^2+1
sage: rot=[a[0] for a in f.roots()]
sage: g=(rot[5]-1)*x^5+(rot[3]*…

All fields are fixed length except for the message itself, so separators are superfluous if fixed-length fields are at the beginning of the token, which now looks like:

In #8998 there was some incorrect documentation added to Cusp.galois_action . This ticket is to fix the documentation. It is also to fix the following error, since in some cases the galois action i…

Let R be a finite ring (up to now: a finite field or Z4). A submodule of Rn is called a linear code of length n. Two linear codes C, C' over R of length n are equivalent, if there is

In gal_reps.py we have
```
sage: EllipticCurve([1,-1,0,-107,-379]).galois_representation().image_type(7) # long time
'The image is a group of order 36.'
```
as doctest. I always get a timeout…

In 4.4.4 the following code produces a number field which is Galois over the rationals but (allegedly) not over an intermediate field.
```
sage: K.=NumberField(x^2+1)
sage: Kt. = K[]
sage: L. = K.e…

I think it would be sensible to move the functions

The attached patch contains some simple code which will return the element of the Galois group of a number field corresponding to complex conjugation (at a specified complex place, or the "default" …

The file ell_rational_field.py is huge and should be split up further. This is especially important for the documentation, currently it is not very user-friendy to find a function in the reference.
