# Computing Galois group of a polynomial?

Here's my attempt so far:

```
x = polygen(QQ, 'x');
K.<z> = NumberField(x^4+x^2+2*x+1)
G = K.galois_group(type='gap')
```

And now I get several pages of error messages beginning with

```
verbose 0 (1780: permgroup_named.py, cardinality) Warning: TransitiveGroups requires the GAP database package. Please install it with ``sage -i database_gap``.
```

However! - I have installed this:

```
install_package()
[...
'database_gap-4.7.4',
...]
```

Anybody got any ideas on where I can go from here?

It woks for me (with Sage 6.4.beta3 and database_gap-4.7.5), i got : Galois group Transitive group number 3 of degree 4 of the Number Field in z with defining polynomial x^4 + x^2 + 2*x + 1 What is your configuration ?
