## Basic invariants

 Dimension: $1$ Group: $C_2$ Conductor: $68= 2^{2} \cdot 17$ Artin number field: Splitting field of $f= x^{2} + 17$ over $\Q$ Size of Galois orbit: 1 Smallest containing permutation representation: $C_2$ Parity: Odd Corresponding Dirichlet character: $$\displaystyle\left(\frac{-68}{\bullet}\right)$$

## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 3 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $1 + 2\cdot 3^{2} + 2\cdot 3^{3} +O\left(3^{ 5 }\right)$ $r_{ 2 }$ $=$ $2 + 2\cdot 3 + 2\cdot 3^{4} +O\left(3^{ 5 }\right)$

### Generators of the action on the roots $r_{ 1 }, r_{ 2 }$

 Cycle notation $(1,2)$
