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:
| $r_{ 1 }$ |
$=$ |
$ 28 a + 16 + \left(17 a + 24\right)\cdot 31 + \left(17 a + 3\right)\cdot 31^{2} + \left(13 a + 11\right)\cdot 31^{3} + \left(a + 22\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 9 a + 27 + \left(15 a + 25\right)\cdot 31 + \left(11 a + 14\right)\cdot 31^{2} + 25\cdot 31^{3} + \left(2 a + 14\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 17 + 7\cdot 31 + 19\cdot 31^{2} + 28\cdot 31^{3} + 29\cdot 31^{4} +O\left(31^{ 5 }\right)$ |

$=$ |
$ 22 a + 14 + \left(15 a + 16\right)\cdot 31 + \left(19 a + 22\right)\cdot 31^{2} + \left(30 a + 14\right)\cdot 31^{3} + \left(28 a + 18\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 6 }$ |
$=$ |
