Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 31 }$ to precision 6.
Roots:

$=$ |
$ 2 + 19\cdot 31 + 11\cdot 31^{2} + 2\cdot 31^{3} + 2\cdot 31^{4} + 20\cdot 31^{5} +O\left(31^{ 6 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 7 + 7\cdot 31 + 31^{2} + 14\cdot 31^{3} + 9\cdot 31^{4} + 29\cdot 31^{5} +O\left(31^{ 6 }\right)$ |
| $r_{ 3 }$ |
$=$ |
