Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 127 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 127 }$: $ x^{2} + 126 x + 3 $

Roots:

$r_{ 1 }$	$=$	$ 39 a + 65 + \left(122 a + 66\right)\cdot 127 + \left(57 a + 110\right)\cdot 127^{2} + \left(29 a + 34\right)\cdot 127^{3} + \left(95 a + 106\right)\cdot 127^{4} +O\left(127^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 92 + 64\cdot 127 + 32\cdot 127^{2} + 23\cdot 127^{3} + 25\cdot 127^{4} +O\left(127^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 12 + 69\cdot 127 + 125\cdot 127^{2} + 63\cdot 127^{3} + 12\cdot 127^{4} +O\left(127^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 94 a + 42 + \left(80 a + 11\right)\cdot 127 + \left(63 a + 16\right)\cdot 127^{2} + \left(7 a + 76\right)\cdot 127^{3} + \left(52 a + 104\right)\cdot 127^{4} +O\left(127^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 33 a + 9 + \left(46 a + 125\right)\cdot 127 + \left(63 a + 125\right)\cdot 127^{2} + \left(119 a + 19\right)\cdot 127^{3} + \left(74 a + 22\right)\cdot 127^{4} +O\left(127^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 57 + 21\cdot 127 + 51\cdot 127^{2} + 29\cdot 127^{3} + 65\cdot 127^{4} +O\left(127^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 88 a + 104 + \left(4 a + 22\right)\cdot 127 + \left(69 a + 46\right)\cdot 127^{2} + \left(97 a + 6\right)\cdot 127^{3} + \left(31 a + 45\right)\cdot 127^{4} +O\left(127^{ 5 }\right)$
