Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 229 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 32 + 87\cdot 229 + 6\cdot 229^{2} + 83\cdot 229^{3} + 182\cdot 229^{4} +O\left(229^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 58 + 48\cdot 229 + 182\cdot 229^{2} + 126\cdot 229^{3} + 209\cdot 229^{4} +O\left(229^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 63 + 147\cdot 229 + 143\cdot 229^{2} + 161\cdot 229^{3} + 3\cdot 229^{4} +O\left(229^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 78 + 175\cdot 229 + 125\cdot 229^{2} + 86\cdot 229^{3} + 62\cdot 229^{4} +O\left(229^{ 5 }\right)$
