Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 5 + 23 + 16\cdot 23^{2} + 3\cdot 23^{3} + 8\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 18 + 21\cdot 23 + 6\cdot 23^{2} + 19\cdot 23^{3} + 14\cdot 23^{4} +O\left(23^{ 5 }\right)$

Generators of the action on the roots $ r_{ 1 }, r_{ 2 } $

Cycle notation
