Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 9 + 7\cdot 31 + 16\cdot 31^{2} + 30\cdot 31^{3} + 11\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 22 + 23\cdot 31 + 14\cdot 31^{2} + 19\cdot 31^{4} +O\left(31^{ 5 }\right)$

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

Cycle notation
