Defining polynomial

$f(x)$

$=$

\(x^{2} - x + 5157\)  .

The roots of $f$ are computed in $\Q_{ 3 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	\( 2\cdot 3^{3} +O(3^{5})\)
$r_{ 2 }$	$=$	\( 1 + 3^{3} + 2\cdot 3^{4} +O(3^{5})\)

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

Cycle notation

$(1,2)$
