Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 79 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 79 }$: $ x^{2} + 78 x + 3 $

Roots:

$r_{ 1 }$	$=$	$ 4 + 24\cdot 79 + 59\cdot 79^{2} + 14\cdot 79^{3} + 75\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 25 a + 13 + \left(41 a + 63\right)\cdot 79 + \left(38 a + 63\right)\cdot 79^{2} + \left(62 a + 22\right)\cdot 79^{3} + \left(21 a + 76\right)\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 37 + 7\cdot 79 + 29\cdot 79^{2} + 22\cdot 79^{3} + 78\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 54 a + 38 + 37 a\cdot 79 + \left(40 a + 61\right)\cdot 79^{2} + \left(16 a + 46\right)\cdot 79^{3} + \left(57 a + 35\right)\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 39 + 18\cdot 79^{2} + 75\cdot 79^{3} + 30\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 51 a + 68 + \left(47 a + 32\right)\cdot 79 + \left(66 a + 72\right)\cdot 79^{2} + 40 a\cdot 79^{3} + \left(74 a + 72\right)\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 28 a + 40 + \left(31 a + 29\right)\cdot 79 + \left(12 a + 12\right)\cdot 79^{2} + \left(38 a + 54\right)\cdot 79^{3} + \left(4 a + 26\right)\cdot 79^{4} +O\left(79^{ 5 }\right)$
