Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 107 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 107 }$: $ x^{2} + 103 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 69 a + 96 + \left(38 a + 104\right)\cdot 107 + \left(41 a + 19\right)\cdot 107^{2} + \left(93 a + 12\right)\cdot 107^{3} + \left(26 a + 96\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 38 a + 51 + \left(68 a + 83\right)\cdot 107 + \left(65 a + 39\right)\cdot 107^{2} + \left(13 a + 23\right)\cdot 107^{3} + \left(80 a + 3\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 105 + 43\cdot 107 + 42\cdot 107^{2} + 84\cdot 107^{3} + 59\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 75 + 50\cdot 107 + 40\cdot 107^{2} + 35\cdot 107^{3} + 7\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 6 + 43\cdot 107 + 89\cdot 107^{2} + 60\cdot 107^{3} + 39\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 65 a + 78 + \left(78 a + 86\right)\cdot 107 + \left(a + 26\right)\cdot 107^{2} + \left(89 a + 89\right)\cdot 107^{3} + \left(10 a + 26\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 42 a + 17 + \left(28 a + 15\right)\cdot 107 + \left(105 a + 62\right)\cdot 107^{2} + \left(17 a + 15\right)\cdot 107^{3} + \left(96 a + 88\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
