Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 383 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 15 + 271\cdot 383 + 354\cdot 383^{2} + 216\cdot 383^{3} + 184\cdot 383^{4} +O\left(383^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 69 + 279\cdot 383 + 234\cdot 383^{2} + 320\cdot 383^{3} + 10\cdot 383^{4} +O\left(383^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 340 + 171\cdot 383 + 304\cdot 383^{2} + 226\cdot 383^{3} + 228\cdot 383^{4} +O\left(383^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 343 + 43\cdot 383 + 255\cdot 383^{2} + 383^{3} + 342\cdot 383^{4} +O\left(383^{ 5 }\right)$
