Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 131 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 131 }$: $ x^{2} + 127 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 130 a + 70 + \left(52 a + 110\right)\cdot 131 + \left(83 a + 70\right)\cdot 131^{2} + \left(30 a + 107\right)\cdot 131^{3} + \left(92 a + 23\right)\cdot 131^{4} +O\left(131^{ 5 }\right)$
$r_{ 2 }$ $=$ $ a + 66 + \left(78 a + 61\right)\cdot 131 + \left(47 a + 89\right)\cdot 131^{2} + \left(100 a + 15\right)\cdot 131^{3} + \left(38 a + 100\right)\cdot 131^{4} +O\left(131^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 116 a + 7 + \left(114 a + 67\right)\cdot 131 + \left(110 a + 105\right)\cdot 131^{2} + \left(29 a + 36\right)\cdot 131^{3} + \left(6 a + 21\right)\cdot 131^{4} +O\left(131^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 15 a + 78 + \left(16 a + 17\right)\cdot 131 + \left(20 a + 41\right)\cdot 131^{2} + \left(101 a + 45\right)\cdot 131^{3} + \left(124 a + 16\right)\cdot 131^{4} +O\left(131^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 113 + 35\cdot 131 + 66\cdot 131^{2} + 86\cdot 131^{3} + 72\cdot 131^{4} +O\left(131^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 109 + 76\cdot 131^{2} + 74\cdot 131^{3} + 48\cdot 131^{4} +O\left(131^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 82 + 99\cdot 131 + 74\cdot 131^{2} + 26\cdot 131^{3} + 110\cdot 131^{4} +O\left(131^{ 5 }\right)$
