Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 83 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 83 }$: $ x^{2} + 82 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 74 a + 19 + \left(48 a + 3\right)\cdot 83 + \left(47 a + 76\right)\cdot 83^{2} + \left(53 a + 3\right)\cdot 83^{3} + \left(67 a + 46\right)\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 3 a + 59 + \left(74 a + 21\right)\cdot 83 + 74\cdot 83^{2} + \left(4 a + 79\right)\cdot 83^{3} + \left(45 a + 81\right)\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 45 + 51\cdot 83 + 7\cdot 83^{2} + 3\cdot 83^{3} + 44\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 9 a + 10 + \left(34 a + 61\right)\cdot 83 + \left(35 a + 74\right)\cdot 83^{2} + \left(29 a + 9\right)\cdot 83^{3} + \left(15 a + 60\right)\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 54 + 18\cdot 83 + 15\cdot 83^{2} + 69\cdot 83^{3} + 59\cdot 83^{4} +O\left(83^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 80 a + 62 + \left(8 a + 9\right)\cdot 83 + \left(82 a + 1\right)\cdot 83^{2} + 78 a\cdot 83^{3} + \left(37 a + 40\right)\cdot 83^{4} +O\left(83^{ 5 }\right)$
