Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 257 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 54 + 21\cdot 257 + 142\cdot 257^{2} + 138\cdot 257^{3} + 153\cdot 257^{4} +O\left(257^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 90 + 102\cdot 257 + 212\cdot 257^{2} + 217\cdot 257^{3} + 210\cdot 257^{4} +O\left(257^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 107 + 6\cdot 257 + 204\cdot 257^{2} + 210\cdot 257^{3} + 181\cdot 257^{4} +O\left(257^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 117 + 113\cdot 257 + 152\cdot 257^{2} + 253\cdot 257^{3} + 223\cdot 257^{4} +O\left(257^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 148 + 13\cdot 257 + 60\cdot 257^{2} + 207\cdot 257^{3} +O\left(257^{ 5 }\right)$
