Galois action

Roots of defining polynomial

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

Roots:

$r_{ 1 }$	$=$	$ 12 + 61 + 57\cdot 61^{2} + 26\cdot 61^{3} + 31\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 21 + 26\cdot 61 + 21\cdot 61^{2} + 59\cdot 61^{3} + 35\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 41 + 34\cdot 61 + 39\cdot 61^{2} + 61^{3} + 25\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 50 + 59\cdot 61 + 3\cdot 61^{2} + 34\cdot 61^{3} + 29\cdot 61^{4} +O\left(61^{ 5 }\right)$
