Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 523 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 89 + 63\cdot 523 + 158\cdot 523^{2} + 424\cdot 523^{3} + 195\cdot 523^{4} +O\left(523^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 221 + 98\cdot 523 + 300\cdot 523^{2} + 7\cdot 523^{3} + 82\cdot 523^{4} +O\left(523^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 361 + 25\cdot 523 + 511\cdot 523^{2} + 100\cdot 523^{3} + 462\cdot 523^{4} +O\left(523^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 437 + 335\cdot 523 + 95\cdot 523^{2} + 349\cdot 523^{3} + 94\cdot 523^{4} +O\left(523^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 462 + 522\cdot 523 + 503\cdot 523^{2} + 163\cdot 523^{3} + 211\cdot 523^{4} +O\left(523^{ 5 }\right)$
