Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 197 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 197 }$: $ x^{2} + 192 x + 2 $

Roots:

$r_{ 1 }$	$=$	$ 146 + 125\cdot 197 + 105\cdot 197^{2} + 138\cdot 197^{3} + 42\cdot 197^{4} +O\left(197^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 157 a + 172 + \left(73 a + 8\right)\cdot 197 + \left(32 a + 55\right)\cdot 197^{2} + \left(76 a + 195\right)\cdot 197^{3} + \left(3 a + 44\right)\cdot 197^{4} +O\left(197^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 160 + 167\cdot 197 + 22\cdot 197^{2} + 12\cdot 197^{3} + 73\cdot 197^{4} +O\left(197^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 98 + 105\cdot 197 + 73\cdot 197^{2} + 145\cdot 197^{3} + 126\cdot 197^{4} +O\left(197^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 165 + 85\cdot 197 + 22\cdot 197^{2} + 57\cdot 197^{3} + 50\cdot 197^{4} +O\left(197^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 40 a + 169 + \left(123 a + 23\right)\cdot 197 + \left(164 a + 143\right)\cdot 197^{2} + \left(120 a + 149\right)\cdot 197^{3} + \left(193 a + 182\right)\cdot 197^{4} +O\left(197^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 76 + 73\cdot 197 + 168\cdot 197^{2} + 89\cdot 197^{3} + 70\cdot 197^{4} +O\left(197^{ 5 }\right)$
