Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 17 }$ to precision 6.
Roots:

$=$ |
$ 1 + 4\cdot 17 + 2\cdot 17^{3} + 10\cdot 17^{4} + 16\cdot 17^{5} +O\left(17^{ 6 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 2 + 6\cdot 17^{2} + 13\cdot 17^{3} + 11\cdot 17^{4} + 13\cdot 17^{5} +O\left(17^{ 6 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 3 + 5\cdot 17 + 13\cdot 17^{2} + 8\cdot 17^{3} + 9\cdot 17^{4} + 5\cdot 17^{5} +O\left(17^{ 6 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 7 + 8\cdot 17 + 4\cdot 17^{2} + 14\cdot 17^{3} + 3\cdot 17^{4} + 6\cdot 17^{5} +O\left(17^{ 6 }\right)$ |
