Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 83 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 15 + 68\cdot 83 + 27\cdot 83^{2} + 30\cdot 83^{3} + 81\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 41 + 70\cdot 83 + 54\cdot 83^{2} + 25\cdot 83^{3} + 55\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 50 + 42\cdot 83 + 44\cdot 83^{2} + 24\cdot 83^{3} + 66\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 61 + 67\cdot 83 + 38\cdot 83^{2} + 2\cdot 83^{3} + 46\cdot 83^{4} +O\left(83^{ 5 }\right)$
