Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 29 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 29 }$: $ x^{2} + 24 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ a + 14 + \left(25 a + 10\right)\cdot 29 + \left(9 a + 25\right)\cdot 29^{2} + \left(4 a + 7\right)\cdot 29^{3} + \left(22 a + 6\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 2 a + 9 + \left(24 a + 13\right)\cdot 29 + \left(13 a + 13\right)\cdot 29^{2} + \left(19 a + 19\right)\cdot 29^{3} + \left(11 a + 16\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 28 a + 19 + \left(3 a + 18\right)\cdot 29 + \left(19 a + 20\right)\cdot 29^{2} + \left(24 a + 19\right)\cdot 29^{3} + \left(6 a + 25\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 2 a + 3 + \left(24 a + 28\right)\cdot 29 + \left(2 a + 11\right)\cdot 29^{2} + \left(17 a + 14\right)\cdot 29^{3} + \left(22 a + 9\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 27 a + 19 + \left(4 a + 15\right)\cdot 29 + 15 a\cdot 29^{2} + \left(9 a + 16\right)\cdot 29^{3} + \left(17 a + 26\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 27 a + 13 + \left(4 a + 1\right)\cdot 29 + \left(26 a + 2\right)\cdot 29^{2} + \left(11 a + 10\right)\cdot 29^{3} + \left(6 a + 18\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 11 + 28\cdot 29 + 12\cdot 29^{2} + 28\cdot 29^{3} + 12\cdot 29^{4} +O\left(29^{ 5 }\right)$
