Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 563 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 62 + 490\cdot 563 + 556\cdot 563^{2} + 137\cdot 563^{3} + 481\cdot 563^{4} +O\left(563^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 92 + 96\cdot 563 + 22\cdot 563^{2} + 500\cdot 563^{3} + 453\cdot 563^{4} +O\left(563^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 119 + 419\cdot 563 + 335\cdot 563^{2} + 36\cdot 563^{3} + 335\cdot 563^{4} +O\left(563^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 322 + 504\cdot 563 + 238\cdot 563^{2} + 528\cdot 563^{3} + 182\cdot 563^{4} +O\left(563^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 531 + 178\cdot 563 + 535\cdot 563^{2} + 485\cdot 563^{3} + 235\cdot 563^{4} +O\left(563^{ 5 }\right)$
