## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 97 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $9 + 11\cdot 97 + 23\cdot 97^{2} + 83\cdot 97^{3} + 59\cdot 97^{4} +O\left(97^{ 5 }\right)$ $r_{ 2 }$ $=$ $13 + 44\cdot 97 + 62\cdot 97^{2} + 38\cdot 97^{3} + 33\cdot 97^{4} +O\left(97^{ 5 }\right)$ $r_{ 3 }$ $=$ $29 + 23\cdot 97 + 65\cdot 97^{2} + 50\cdot 97^{3} + 3\cdot 97^{4} +O\left(97^{ 5 }\right)$ $r_{ 4 }$ $=$ $46 + 18\cdot 97 + 43\cdot 97^{2} + 21\cdot 97^{3} +O\left(97^{ 5 }\right)$
