Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 193 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 193 }$: $ x^{2} + 192 x + 5 $

Roots:

$r_{ 1 }$	$=$	$ 127 a + \left(88 a + 53\right)\cdot 193 + \left(192 a + 177\right)\cdot 193^{2} + \left(77 a + 118\right)\cdot 193^{3} + \left(45 a + 18\right)\cdot 193^{4} +O\left(193^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 66 a + 127 + \left(104 a + 14\right)\cdot 193 + 88\cdot 193^{2} + \left(115 a + 4\right)\cdot 193^{3} + \left(147 a + 179\right)\cdot 193^{4} +O\left(193^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 27 + 156\cdot 193 + 2\cdot 193^{2} + 175\cdot 193^{3} + 163\cdot 193^{4} +O\left(193^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 138 + 63\cdot 193 + 58\cdot 193^{2} + 86\cdot 193^{3} + 170\cdot 193^{4} +O\left(193^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 54 + 85\cdot 193 + 51\cdot 193^{2} + 120\cdot 193^{3} + 34\cdot 193^{4} +O\left(193^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 19 + 131\cdot 193 + 34\cdot 193^{2} + 134\cdot 193^{3} + 57\cdot 193^{4} +O\left(193^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 23 + 75\cdot 193 + 166\cdot 193^{2} + 132\cdot 193^{3} + 147\cdot 193^{4} +O\left(193^{ 5 }\right)$
