Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 31 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 31 }$: $ x^{2} + 29 x + 3 $
Roots:
| $r_{ 1 }$ |
$=$ |

| $r_{ 2 }$ |
$=$ |
$ 22 + 26\cdot 31 + 25\cdot 31^{2} + 25\cdot 31^{3} + 20\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
