Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 41 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 18 + 38\cdot 41 + 9\cdot 41^{2} + 36\cdot 41^{3} + 39\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 20 + 40\cdot 41 + 20\cdot 41^{2} + 5\cdot 41^{3} + 28\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 21 + 9\cdot 41 + 16\cdot 41^{2} + 20\cdot 41^{3} + 32\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 24 + 34\cdot 41 + 34\cdot 41^{2} + 19\cdot 41^{3} + 22\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
