Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 211 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 211 }$: $ x^{2} + 207 x + 2 $

Roots:

$r_{ 1 }$	$=$	$ 185 a + 115 + \left(147 a + 159\right)\cdot 211 + \left(157 a + 90\right)\cdot 211^{2} + \left(134 a + 22\right)\cdot 211^{3} + \left(91 a + 49\right)\cdot 211^{4} +O\left(211^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 35 + 122\cdot 211 + 141\cdot 211^{2} + 115\cdot 211^{3} + 183\cdot 211^{4} +O\left(211^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 26 a + 11 + \left(63 a + 144\right)\cdot 211 + \left(53 a + 151\right)\cdot 211^{2} + \left(76 a + 192\right)\cdot 211^{3} + \left(119 a + 69\right)\cdot 211^{4} +O\left(211^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 201 a + 132 + \left(84 a + 8\right)\cdot 211 + \left(27 a + 80\right)\cdot 211^{2} + 102 a\cdot 211^{3} + \left(172 a + 25\right)\cdot 211^{4} +O\left(211^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 195 + 165\cdot 211 + 176\cdot 211^{2} + 142\cdot 211^{3} + 202\cdot 211^{4} +O\left(211^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 54 + 96\cdot 211 + 98\cdot 211^{2} + 199\cdot 211^{3} + 122\cdot 211^{4} +O\left(211^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 10 a + 92 + \left(126 a + 147\right)\cdot 211 + \left(183 a + 104\right)\cdot 211^{2} + \left(108 a + 170\right)\cdot 211^{3} + \left(38 a + 190\right)\cdot 211^{4} +O\left(211^{ 5 }\right)$
