Galois action

Roots of defining polynomial

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

Roots:

$r_{ 1 }$	$=$	$ 14 + 14\cdot 29 + 7\cdot 29^{2} + 7\cdot 29^{3} + 27\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 15 + 14\cdot 29 + 21\cdot 29^{2} + 21\cdot 29^{3} + 29^{4} +O\left(29^{ 5 }\right)$

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