Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 157 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 4 + 16\cdot 157 + 26\cdot 157^{2} + 56\cdot 157^{3} + 47\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 83 + 48\cdot 157 + 47\cdot 157^{2} + 137\cdot 157^{3} + 127\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 101 + 47\cdot 157 + 104\cdot 157^{2} + 16\cdot 157^{3} + 135\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 126 + 44\cdot 157 + 136\cdot 157^{2} + 103\cdot 157^{3} + 3\cdot 157^{4} +O\left(157^{ 5 }\right)$ |
