## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 7 }$ to precision 5.
Roots: \begin{aligned} r_{ 1 } &= 2 + 3\cdot 7 + 6\cdot 7^{2} + 3\cdot 7^{3} + 3\cdot 7^{4} +O\left(7^{ 5 }\right) \\ r_{ 2 } &= 6 + 3\cdot 7 + 3\cdot 7^{3} + 3\cdot 7^{4} +O\left(7^{ 5 }\right) \\ \end{aligned}
