Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 359 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 92 + 114\cdot 359 + 330\cdot 359^{2} + 41\cdot 359^{3} + 294\cdot 359^{4} +O\left(359^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 145 + 128\cdot 359 + 341\cdot 359^{2} + 213\cdot 359^{3} + 110\cdot 359^{4} +O\left(359^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 152 + 154\cdot 359 + 96\cdot 359^{2} + 110\cdot 359^{3} + 56\cdot 359^{4} +O\left(359^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 329 + 320\cdot 359 + 308\cdot 359^{2} + 351\cdot 359^{3} + 256\cdot 359^{4} +O\left(359^{ 5 }\right)$
