Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 311 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 103 + 309\cdot 311 + 174\cdot 311^{2} + 194\cdot 311^{3} + 9\cdot 311^{4} +O\left(311^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 134 + 140\cdot 311 + 113\cdot 311^{2} + 174\cdot 311^{3} + 176\cdot 311^{4} +O\left(311^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 155 + 198\cdot 311 + 201\cdot 311^{2} + 265\cdot 311^{3} + 4\cdot 311^{4} +O\left(311^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 255 + 185\cdot 311 + 282\cdot 311^{2} + 94\cdot 311^{3} + 219\cdot 311^{4} +O\left(311^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 287 + 98\cdot 311 + 160\cdot 311^{2} + 203\cdot 311^{3} + 211\cdot 311^{4} +O\left(311^{ 5 }\right)$
