Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 41 }$ to precision 5.
Roots:

$=$ |
$ 1 + 21\cdot 41 + 5\cdot 41^{2} + 41^{3} + 21\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 3 + 20\cdot 41 + 37\cdot 41^{2} + 34\cdot 41^{3} + 26\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 10 + 28\cdot 41 + 8\cdot 41^{2} + 13\cdot 41^{3} + 18\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 26 + 6\cdot 41 + 25\cdot 41^{2} + 13\cdot 41^{3} + 14\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
