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:

$r_{ 1 }$	$=$	$ 9 + 122\cdot 191 + 13\cdot 191^{2} + 80\cdot 191^{3} + 123\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 164 + 101\cdot 191 + 54\cdot 191^{2} + 4\cdot 191^{3} + 182\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 151 + 11\cdot 191 + 81\cdot 191^{2} + 74\cdot 191^{3} + 118\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 68 a + 76 + \left(94 a + 116\right)\cdot 191 + \left(183 a + 115\right)\cdot 191^{2} + \left(163 a + 18\right)\cdot 191^{3} + \left(126 a + 72\right)\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 179 + 102\cdot 191 + 171\cdot 191^{2} + 138\cdot 191^{3} + 69\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 123 a + 144 + \left(96 a + 142\right)\cdot 191 + \left(7 a + 13\right)\cdot 191^{2} + \left(27 a + 190\right)\cdot 191^{3} + \left(64 a + 34\right)\cdot 191^{4} +O\left(191^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 41 + 166\cdot 191 + 122\cdot 191^{2} + 66\cdot 191^{3} + 163\cdot 191^{4} +O\left(191^{ 5 }\right)$
