Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 499 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 499 }$: $ x^{2} + 493 x + 7 $

Roots:

$r_{ 1 }$	$=$	$ 22 a + 40 + \left(438 a + 386\right)\cdot 499 + \left(151 a + 357\right)\cdot 499^{2} + \left(445 a + 202\right)\cdot 499^{3} + \left(269 a + 400\right)\cdot 499^{4} +O\left(499^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 477 a + 172 + \left(60 a + 497\right)\cdot 499 + \left(347 a + 331\right)\cdot 499^{2} + \left(53 a + 227\right)\cdot 499^{3} + \left(229 a + 77\right)\cdot 499^{4} +O\left(499^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 116 + 307\cdot 499 + 156\cdot 499^{2} + 237\cdot 499^{3} + 223\cdot 499^{4} +O\left(499^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 165 a + 449 + \left(240 a + 348\right)\cdot 499 + \left(343 a + 343\right)\cdot 499^{2} + \left(396 a + 347\right)\cdot 499^{3} + \left(39 a + 104\right)\cdot 499^{4} +O\left(499^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 334 a + 441 + \left(258 a + 128\right)\cdot 499 + \left(155 a + 168\right)\cdot 499^{2} + \left(102 a + 388\right)\cdot 499^{3} + \left(459 a + 445\right)\cdot 499^{4} +O\left(499^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 267 + 81\cdot 499 + 292\cdot 499^{2} + 471\cdot 499^{3} + 450\cdot 499^{4} +O\left(499^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 13 + 246\cdot 499 + 345\cdot 499^{2} + 120\cdot 499^{3} + 293\cdot 499^{4} +O\left(499^{ 5 }\right)$
