Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 191 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 191 }$: $ x^{2} + 190 x + 19 $

Roots:

$r_{ 1 }$	$=$	$ 155 + 112\cdot 191 + 159\cdot 191^{2} + 163\cdot 191^{3} + 65\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 7 a + 93 + \left(39 a + 139\right)\cdot 191 + \left(44 a + 179\right)\cdot 191^{2} + \left(185 a + 41\right)\cdot 191^{3} + \left(13 a + 140\right)\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 175 + 160\cdot 191 + 180\cdot 191^{2} + 54\cdot 191^{3} + 42\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 158 + 126\cdot 191 + 115\cdot 191^{2} + 133\cdot 191^{3} +O\left(191^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 24 a + 126 + 133\cdot 191 + \left(98 a + 113\right)\cdot 191^{2} + \left(99 a + 92\right)\cdot 191^{3} + \left(112 a + 75\right)\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 184 a + 100 + \left(151 a + 171\right)\cdot 191 + \left(146 a + 184\right)\cdot 191^{2} + \left(5 a + 182\right)\cdot 191^{3} + \left(177 a + 159\right)\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 167 a + 150 + \left(190 a + 109\right)\cdot 191 + \left(92 a + 20\right)\cdot 191^{2} + \left(91 a + 94\right)\cdot 191^{3} + \left(78 a + 88\right)\cdot 191^{4} +O\left(191^{ 5 }\right)$
