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:

$=$ |
$ 10 a + 1 + \left(19 a + 13\right)\cdot 31 + \left(17 a + 14\right)\cdot 31^{2} + \left(29 a + 7\right)\cdot 31^{3} + \left(20 a + 5\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 4 + 22\cdot 31 + 25\cdot 31^{2} + 18\cdot 31^{3} + 28\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |

| $r_{ 5 }$ |
$=$ |
$ 23 + 11\cdot 31 + 11\cdot 31^{2} + 27\cdot 31^{3} + 26\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 6 }$ |
$=$ |
