Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 157 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 4 + 101\cdot 157 + 82\cdot 157^{2} + 42\cdot 157^{3} + 130\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 40 + 90\cdot 157 + 111\cdot 157^{2} + 13\cdot 157^{3} + 79\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 44 + 118\cdot 157 + 36\cdot 157^{2} + 63\cdot 157^{3} + 93\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 69 + 4\cdot 157 + 83\cdot 157^{2} + 37\cdot 157^{3} + 11\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
