Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 181 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 181 }$: $ x^{2} + 177 x + 2 $

Roots:

$r_{ 1 }$	$=$	$ 7 + 156\cdot 181 + 139\cdot 181^{2} + 8\cdot 181^{3} + 138\cdot 181^{4} +O\left(181^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 96 a + 173 + \left(125 a + 54\right)\cdot 181 + \left(162 a + 138\right)\cdot 181^{2} + \left(78 a + 16\right)\cdot 181^{3} + \left(165 a + 175\right)\cdot 181^{4} +O\left(181^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 90 a + 173 + \left(95 a + 109\right)\cdot 181 + \left(121 a + 179\right)\cdot 181^{2} + \left(77 a + 36\right)\cdot 181^{3} + \left(29 a + 22\right)\cdot 181^{4} +O\left(181^{ 5 }\right)$
