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:
$r_{ 1 }$ $=$ $ 8 + 42\cdot 53 + 47\cdot 53^{2} + 14\cdot 53^{3} + 2\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 33 a + 43 + \left(44 a + 9\right)\cdot 53 + \left(37 a + 9\right)\cdot 53^{2} + \left(8 a + 16\right)\cdot 53^{3} + \left(30 a + 39\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 44 + 45\cdot 53 + 12\cdot 53^{2} + 19\cdot 53^{3} + 10\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 50 a + 4 + \left(36 a + 10\right)\cdot 53 + \left(40 a + 3\right)\cdot 53^{2} + \left(26 a + 41\right)\cdot 53^{3} + \left(13 a + 43\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 3 a + 45 + \left(16 a + 1\right)\cdot 53 + \left(12 a + 23\right)\cdot 53^{2} + \left(26 a + 1\right)\cdot 53^{3} + \left(39 a + 18\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 20 a + 16 + \left(8 a + 49\right)\cdot 53 + \left(15 a + 9\right)\cdot 53^{2} + \left(44 a + 13\right)\cdot 53^{3} + \left(22 a + 45\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
