Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 359 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 25 + 13\cdot 359 + 219\cdot 359^{2} + 48\cdot 359^{3} + 44\cdot 359^{4} +O\left(359^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 27 + 44\cdot 359 + 54\cdot 359^{2} + 88\cdot 359^{3} + 320\cdot 359^{4} +O\left(359^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 64 + 115\cdot 359 + 91\cdot 359^{2} + 142\cdot 359^{3} + 258\cdot 359^{4} +O\left(359^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 293 + 173\cdot 359 + 139\cdot 359^{2} + 62\cdot 359^{3} + 260\cdot 359^{4} +O\left(359^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 310 + 12\cdot 359 + 214\cdot 359^{2} + 17\cdot 359^{3} + 194\cdot 359^{4} +O\left(359^{ 5 }\right)$
