Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 257 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 88 + 97\cdot 257 + 125\cdot 257^{2} + 227\cdot 257^{3} + 87\cdot 257^{4} +O\left(257^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 179 + 141\cdot 257 + 108\cdot 257^{2} + 159\cdot 257^{3} + 104\cdot 257^{4} +O\left(257^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 251 + 120\cdot 257 + 229\cdot 257^{2} + 86\cdot 257^{3} + 33\cdot 257^{4} +O\left(257^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 253 + 153\cdot 257 + 50\cdot 257^{2} + 40\cdot 257^{3} + 31\cdot 257^{4} +O\left(257^{ 5 }\right)$ |
Generators of the action on the roots
$r_1, \ldots, r_{ 4 }$
| Cycle notation |
| $(1,2,3,4)$ |
