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

$=$ |
$ 5 + 46\cdot 89 + 58\cdot 89^{2} + 5\cdot 89^{3} + 13\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 8 + 88\cdot 89 + 86\cdot 89^{2} + 83\cdot 89^{3} + 81\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 30 + 86\cdot 89 + 73\cdot 89^{2} + 54\cdot 89^{3} + 41\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 48 + 46\cdot 89 + 47\cdot 89^{2} + 33\cdot 89^{3} + 41\cdot 89^{4} +O\left(89^{ 5 }\right)$ |
| $r_{ 5 }$ |
