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:
$r_{ 1 }$ $=$ $ 8 a + 31 + \left(33 a + 40\right)\cdot 41 + \left(14 a + 36\right)\cdot 41^{2} + \left(a + 2\right)\cdot 41^{3} + \left(a + 32\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 33 + 22\cdot 41 + 8\cdot 41^{2} + 3\cdot 41^{3} + 33\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 17 a + 19 + \left(36 a + 28\right)\cdot 41 + \left(37 a + 7\right)\cdot 41^{2} + \left(40 a + 1\right)\cdot 41^{3} + \left(13 a + 24\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 24 a + 29 + \left(4 a + 38\right)\cdot 41 + \left(3 a + 2\right)\cdot 41^{2} + 4\cdot 41^{3} + \left(27 a + 25\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 38 + 23\cdot 41 + 18\cdot 41^{2} + 37\cdot 41^{3} + 15\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 33 a + 14 + \left(7 a + 9\right)\cdot 41 + \left(26 a + 7\right)\cdot 41^{2} + \left(39 a + 33\right)\cdot 41^{3} + \left(39 a + 33\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$
