## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 317 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $116 + 117\cdot 317 + 120\cdot 317^{2} + 83\cdot 317^{3} + 188\cdot 317^{4} +O\left(317^{ 5 }\right)$ $r_{ 2 }$ $=$ $168 + 199\cdot 317 + 307\cdot 317^{2} + 80\cdot 317^{3} + 173\cdot 317^{4} +O\left(317^{ 5 }\right)$ $r_{ 3 }$ $=$ $170 + 64\cdot 317 + 126\cdot 317^{2} + 41\cdot 317^{3} + 56\cdot 317^{4} +O\left(317^{ 5 }\right)$ $r_{ 4 }$ $=$ $181 + 252\cdot 317 + 79\cdot 317^{2} + 111\cdot 317^{3} + 216\cdot 317^{4} +O\left(317^{ 5 }\right)$
