Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 59 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 7 + 41\cdot 59 + 48\cdot 59^{2} + 13\cdot 59^{3} + 42\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 18 + 56\cdot 59 + 2\cdot 59^{2} + 39\cdot 59^{3} + 33\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 41 + 2\cdot 59 + 56\cdot 59^{2} + 19\cdot 59^{3} + 25\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 52 + 17\cdot 59 + 10\cdot 59^{2} + 45\cdot 59^{3} + 16\cdot 59^{4} +O\left(59^{ 5 }\right)$
