Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 59 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 59 }$: $ x^{2} + 58 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 49 a + 16 + \left(42 a + 6\right)\cdot 59 + \left(13 a + 19\right)\cdot 59^{2} + \left(5 a + 11\right)\cdot 59^{3} + \left(40 a + 47\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 44 + 49\cdot 59 + 25\cdot 59^{2} + 3\cdot 59^{3} + 24\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 57 + 4\cdot 59 + 29\cdot 59^{2} + 52\cdot 59^{3} + 32\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 57 a + \left(25 a + 44\right)\cdot 59 + \left(30 a + 24\right)\cdot 59^{2} + \left(31 a + 23\right)\cdot 59^{3} + \left(4 a + 38\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 2 a + 57 + \left(33 a + 12\right)\cdot 59 + \left(28 a + 29\right)\cdot 59^{2} + \left(27 a + 24\right)\cdot 59^{3} + \left(54 a + 11\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 10 a + 6 + 16 a\cdot 59 + \left(45 a + 49\right)\cdot 59^{2} + \left(53 a + 2\right)\cdot 59^{3} + \left(18 a + 23\right)\cdot 59^{4} +O\left(59^{ 5 }\right)$
