Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 41 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 12 + 14\cdot 41 + 34\cdot 41^{2} + 3\cdot 41^{3} + 37\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 16 + 33\cdot 41 + 5\cdot 41^{2} + 34\cdot 41^{3} + 32\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 26 + 7\cdot 41 + 35\cdot 41^{2} + 6\cdot 41^{3} + 8\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 30 + 26\cdot 41 + 6\cdot 41^{2} + 37\cdot 41^{3} + 3\cdot 41^{4} +O\left(41^{ 5 }\right)$
