Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 43 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 8 + 29\cdot 43 + 9\cdot 43^{2} + 33\cdot 43^{3} + 29\cdot 43^{4} +O\left(43^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 24 + 15\cdot 43 + 35\cdot 43^{2} + 28\cdot 43^{3} + 31\cdot 43^{4} +O\left(43^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 26 + 19\cdot 43 + 12\cdot 43^{2} + 31\cdot 43^{3} + 20\cdot 43^{4} +O\left(43^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 29 + 21\cdot 43 + 28\cdot 43^{2} + 35\cdot 43^{3} + 3\cdot 43^{4} +O\left(43^{ 5 }\right)$
