Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 223 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 54 + 208\cdot 223 + 219\cdot 223^{2} + 181\cdot 223^{3} + 25\cdot 223^{4} +O\left(223^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 66 + 8\cdot 223 + 139\cdot 223^{2} + 62\cdot 223^{3} + 31\cdot 223^{4} +O\left(223^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 143 + 57\cdot 223 + 213\cdot 223^{2} + 107\cdot 223^{3} + 94\cdot 223^{4} +O\left(223^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 184 + 171\cdot 223 + 96\cdot 223^{2} + 93\cdot 223^{3} + 71\cdot 223^{4} +O\left(223^{ 5 }\right)$
