Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 6.

Roots:

$r_{ 1 }$	$=$	$ 9 + 16\cdot 31 + 2\cdot 31^{2} + 12\cdot 31^{3} + 22\cdot 31^{4} + 4\cdot 31^{5} +O\left(31^{ 6 }\right)$
$r_{ 2 }$	$=$	$ 10 + 13\cdot 31 + 7\cdot 31^{2} + 3\cdot 31^{3} + 15\cdot 31^{4} + 25\cdot 31^{5} +O\left(31^{ 6 }\right)$
$r_{ 3 }$	$=$	$ 18 + 25\cdot 31 + 8\cdot 31^{2} + 23\cdot 31^{3} + 9\cdot 31^{4} + 26\cdot 31^{5} +O\left(31^{ 6 }\right)$
$r_{ 4 }$	$=$	$ 26 + 6\cdot 31 + 12\cdot 31^{2} + 23\cdot 31^{3} + 14\cdot 31^{4} + 5\cdot 31^{5} +O\left(31^{ 6 }\right)$
