Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 89 }$ to precision 5.
Roots:

$=$ |
$ 17 + 8\cdot 89 + 32\cdot 89^{2} + 36\cdot 89^{3} + 10\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 25 + 13\cdot 89 + 22\cdot 89^{2} + 46\cdot 89^{3} + 21\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 28 + 2\cdot 89 + 80\cdot 89^{2} + 4\cdot 89^{3} + 52\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 41 + 26\cdot 89 + 71\cdot 89^{2} + 39\cdot 89^{3} + 54\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
