Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 29 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 5 + 19\cdot 29 + 6\cdot 29^{2} + 23\cdot 29^{3} + 17\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 11 + 4\cdot 29 + 13\cdot 29^{2} + 14\cdot 29^{3} + 19\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 17 + 13\cdot 29 + 21\cdot 29^{2} + 20\cdot 29^{3} + 5\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 26 + 20\cdot 29 + 16\cdot 29^{2} + 28\cdot 29^{3} + 14\cdot 29^{4} +O\left(29^{ 5 }\right)$
