Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 53 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 53 }$: $ x^{2} + 49 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 16 + 39\cdot 53 + 17\cdot 53^{2} + 46\cdot 53^{3} + 6\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 28 a + 39 + \left(38 a + 10\right)\cdot 53 + \left(27 a + 39\right)\cdot 53^{2} + \left(39 a + 38\right)\cdot 53^{3} + \left(10 a + 2\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 25 a + 45 + \left(14 a + 30\right)\cdot 53 + \left(25 a + 5\right)\cdot 53^{2} + \left(13 a + 10\right)\cdot 53^{3} + \left(42 a + 6\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 48 a + 49 + \left(34 a + 5\right)\cdot 53 + \left(32 a + 8\right)\cdot 53^{2} + \left(25 a + 48\right)\cdot 53^{3} + \left(44 a + 3\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 5 a + 29 + \left(18 a + 44\right)\cdot 53 + \left(20 a + 50\right)\cdot 53^{2} + \left(27 a + 11\right)\cdot 53^{3} + \left(8 a + 50\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 42 + 35\cdot 53 + 38\cdot 53^{2} + 31\cdot 53^{3} + 34\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 46 + 44\cdot 53 + 51\cdot 53^{2} + 24\cdot 53^{3} + 53^{4} +O\left(53^{ 5 }\right)$
