Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 61 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 5 + 58\cdot 61 + 44\cdot 61^{2} + 58\cdot 61^{3} + 28\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 23 + 23\cdot 61 + 6\cdot 61^{2} + 12\cdot 61^{3} + 53\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 38 + 37\cdot 61 + 54\cdot 61^{2} + 48\cdot 61^{3} + 7\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 56 + 2\cdot 61 + 16\cdot 61^{2} + 2\cdot 61^{3} + 32\cdot 61^{4} +O\left(61^{ 5 }\right)$
