Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 41 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 41 }$: $ x^{2} + 38 x + 6 $
Roots:
$r_{ 1 }$ $=$ $ 6 + 28\cdot 41 + 15\cdot 41^{3} + 38\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 3 + 37\cdot 41 + 28\cdot 41^{2} + 15\cdot 41^{3} + 23\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 20 a + 6 + \left(11 a + 11\right)\cdot 41 + \left(4 a + 20\right)\cdot 41^{2} + \left(39 a + 16\right)\cdot 41^{3} + \left(27 a + 25\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 25 a + 25 + 28 a\cdot 41 + \left(39 a + 1\right)\cdot 41^{2} + \left(11 a + 16\right)\cdot 41^{3} + \left(38 a + 13\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 21 a + 25 + \left(29 a + 25\right)\cdot 41 + \left(36 a + 21\right)\cdot 41^{2} + \left(a + 6\right)\cdot 41^{3} + \left(13 a + 29\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 16 a + 18 + \left(12 a + 20\right)\cdot 41 + \left(a + 9\right)\cdot 41^{2} + \left(29 a + 12\right)\cdot 41^{3} + \left(2 a + 34\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
