## Basic invariants

 Dimension: $1$ Group: $C_3$ Conductor: $$19$$ Artin field: Galois closure of 3.3.361.1 Galois orbit size: $2$ Smallest permutation container: $C_3$ Parity: even Dirichlet character: $$\chi_{19}(7,\cdot)$$ Projective image: $C_1$ Projective field: Galois closure of $$\Q$$

## Defining polynomial

 $f(x)$ $=$ $$x^{3} - x^{2} - 6x + 7$$ x^3 - x^2 - 6*x + 7 .

The roots of $f$ are computed in $\Q_{ 7 }$ to precision 5.

Roots:
 $r_{ 1 }$ $=$ $$6\cdot 7 + 6\cdot 7^{2} + 6\cdot 7^{4} +O(7^{5})$$ 6*7 + 6*7^2 + 6*7^4+O(7^5) $r_{ 2 }$ $=$ $$3 + 6\cdot 7 + 5\cdot 7^{4} +O(7^{5})$$ 3 + 6*7 + 5*7^4+O(7^5) $r_{ 3 }$ $=$ $$5 + 7 + 6\cdot 7^{2} + 5\cdot 7^{3} + 2\cdot 7^{4} +O(7^{5})$$ 5 + 7 + 6*7^2 + 5*7^3 + 2*7^4+O(7^5)
