Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 59 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 59 }$: $ x^{2} + 58 x + 2 $

Roots:

$r_{ 1 }$	$=$	$ 50 + 40\cdot 59 + 32\cdot 59^{2} + 49\cdot 59^{3} + 32\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 27 a + 8 + \left(17 a + 12\right)\cdot 59 + \left(14 a + 1\right)\cdot 59^{2} + \left(2 a + 5\right)\cdot 59^{3} + \left(50 a + 35\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 46 + 12\cdot 59 + 19\cdot 59^{2} + 55\cdot 59^{3} + 7\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 32 a + 35 + \left(41 a + 2\right)\cdot 59 + \left(44 a + 57\right)\cdot 59^{2} + \left(56 a + 51\right)\cdot 59^{3} + \left(8 a + 23\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 47 + 38\cdot 59 + 42\cdot 59^{2} + 8\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 29 a + 11 + \left(11 a + 14\right)\cdot 59 + \left(52 a + 21\right)\cdot 59^{2} + \left(38 a + 43\right)\cdot 59^{3} + \left(18 a + 44\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 30 a + 40 + \left(47 a + 55\right)\cdot 59 + \left(6 a + 2\right)\cdot 59^{2} + \left(20 a + 30\right)\cdot 59^{3} + \left(40 a + 24\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
