Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 41 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 5 + 30\cdot 41 + 18\cdot 41^{2} + 20\cdot 41^{3} + 39\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 21 + 34\cdot 41 + 40\cdot 41^{2} + 32\cdot 41^{3} +O\left(41^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 24 + 30\cdot 41 + 16\cdot 41^{2} + 41^{3} + 4\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 33 + 27\cdot 41 + 5\cdot 41^{2} + 27\cdot 41^{3} + 37\cdot 41^{4} +O\left(41^{ 5 }\right)$
