Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 43 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 43 }$: $ x^{2} + 42 x + 3 $
Roots:

$=$ |
$ 7 a + 13 + \left(18 a + 7\right)\cdot 43 + \left(7 a + 32\right)\cdot 43^{2} + \left(13 a + 8\right)\cdot 43^{3} + \left(9 a + 40\right)\cdot 43^{4} +O\left(43^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 32 + 39\cdot 43 + 22\cdot 43^{2} + 3\cdot 43^{3} + 29\cdot 43^{4} +O\left(43^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 4 + 24\cdot 43 + 23\cdot 43^{2} + 41\cdot 43^{3} + 41\cdot 43^{4} +O\left(43^{ 5 }\right)$ |

| $r_{ 5 }$ |
$=$ |
$ 23 a + 20 + 18 a\cdot 43 + \left(18 a + 36\right)\cdot 43^{2} + \left(5 a + 36\right)\cdot 43^{3} + \left(36 a + 39\right)\cdot 43^{4} +O\left(43^{ 5 }\right)$ |
