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:
$r_{ 1 }$ $=$ $ 106 a + 24 + \left(99 a + 79\right)\cdot 107 + \left(4 a + 61\right)\cdot 107^{2} + \left(69 a + 99\right)\cdot 107^{3} + \left(31 a + 60\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 55 a + 3 + \left(96 a + 6\right)\cdot 107 + \left(58 a + 22\right)\cdot 107^{2} + \left(106 a + 91\right)\cdot 107^{3} + \left(75 a + 3\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 82 + 73\cdot 107 + 97\cdot 107^{2} + 78\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 52 a + 9 + \left(10 a + 16\right)\cdot 107 + \left(48 a + 54\right)\cdot 107^{2} + 30\cdot 107^{3} + \left(31 a + 94\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 79 + 93\cdot 107 + 103\cdot 107^{2} + 48\cdot 107^{3} + 72\cdot 107^{4} +O\left(107^{ 5 }\right)$
$r_{ 6 }$ $=$ $ a + 20 + \left(7 a + 52\right)\cdot 107 + \left(102 a + 88\right)\cdot 107^{2} + \left(37 a + 49\right)\cdot 107^{3} + \left(75 a + 11\right)\cdot 107^{4} +O\left(107^{ 5 }\right)$
