Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 353 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 353 }$: $ x^{2} + 348 x + 3 $

Roots:

$r_{ 1 }$	$=$	$ 232 a + 227 + \left(27 a + 2\right)\cdot 353 + \left(298 a + 81\right)\cdot 353^{2} + \left(349 a + 121\right)\cdot 353^{3} + \left(152 a + 338\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 118 a + 151 + \left(107 a + 162\right)\cdot 353 + \left(302 a + 132\right)\cdot 353^{2} + \left(134 a + 105\right)\cdot 353^{3} + \left(84 a + 279\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 243 + 159\cdot 353 + 14\cdot 353^{2} + 247\cdot 353^{3} + 192\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 121 a + 328 + \left(325 a + 261\right)\cdot 353 + \left(54 a + 131\right)\cdot 353^{2} + \left(3 a + 160\right)\cdot 353^{3} + \left(200 a + 47\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 130 + 229\cdot 353 + 177\cdot 353^{2} + 315\cdot 353^{3} + 193\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 298 + 14\cdot 353 + 44\cdot 353^{2} + 338\cdot 353^{3} + 146\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 235 a + 35 + \left(245 a + 228\right)\cdot 353 + \left(50 a + 124\right)\cdot 353^{2} + \left(218 a + 124\right)\cdot 353^{3} + \left(268 a + 213\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
