Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 29 }$ to precision 8.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 29 }$: $ x^{2} + 24 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 4 + 4\cdot 29 + 6\cdot 29^{2} + 12\cdot 29^{3} + 27\cdot 29^{4} + 8\cdot 29^{5} + 7\cdot 29^{6} + 17\cdot 29^{7} +O\left(29^{ 8 }\right)$
$r_{ 2 }$ $=$ $ 8 a + 5 + \left(20 a + 5\right)\cdot 29 + \left(13 a + 27\right)\cdot 29^{2} + \left(16 a + 28\right)\cdot 29^{3} + \left(14 a + 4\right)\cdot 29^{4} + \left(10 a + 18\right)\cdot 29^{5} + \left(18 a + 6\right)\cdot 29^{6} + \left(3 a + 5\right)\cdot 29^{7} +O\left(29^{ 8 }\right)$
$r_{ 3 }$ $=$ $ 21 a + 16 + \left(8 a + 11\right)\cdot 29 + \left(15 a + 17\right)\cdot 29^{2} + \left(12 a + 10\right)\cdot 29^{3} + \left(14 a + 3\right)\cdot 29^{4} + \left(18 a + 27\right)\cdot 29^{5} + 10 a\cdot 29^{6} + \left(25 a + 5\right)\cdot 29^{7} +O\left(29^{ 8 }\right)$
$r_{ 4 }$ $=$ $ 21 a + 8 + \left(a + 10\right)\cdot 29 + \left(18 a + 17\right)\cdot 29^{2} + \left(8 a + 19\right)\cdot 29^{3} + \left(13 a + 25\right)\cdot 29^{4} + \left(13 a + 3\right)\cdot 29^{5} + \left(24 a + 25\right)\cdot 29^{6} + \left(23 a + 25\right)\cdot 29^{7} +O\left(29^{ 8 }\right)$
$r_{ 5 }$ $=$ $ 8 a + 26 + \left(27 a + 26\right)\cdot 29 + \left(10 a + 18\right)\cdot 29^{2} + \left(20 a + 15\right)\cdot 29^{3} + \left(15 a + 25\right)\cdot 29^{4} + \left(15 a + 28\right)\cdot 29^{5} + \left(4 a + 17\right)\cdot 29^{6} + \left(5 a + 4\right)\cdot 29^{7} +O\left(29^{ 8 }\right)$
