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:
$r_{ 1 }$ $=$ $ 44 a + 35 + \left(25 a + 4\right)\cdot 53 + \left(49 a + 10\right)\cdot 53^{2} + \left(11 a + 34\right)\cdot 53^{3} + 35\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 14 + 21\cdot 53 + 16\cdot 53^{2} + 29\cdot 53^{3} + 35\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 9 a + 52 + \left(27 a + 10\right)\cdot 53 + \left(3 a + 23\right)\cdot 53^{2} + \left(41 a + 32\right)\cdot 53^{3} + \left(52 a + 24\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 52 a + 51 + \left(41 a + 51\right)\cdot 53 + \left(20 a + 39\right)\cdot 53^{2} + \left(31 a + 47\right)\cdot 53^{3} + \left(25 a + 16\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 31 + 2\cdot 53 + 52\cdot 53^{2} + 10\cdot 53^{3} + 26\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 6 }$ $=$ $ a + 47 + \left(11 a + 8\right)\cdot 53 + \left(32 a + 28\right)\cdot 53^{2} + \left(21 a + 46\right)\cdot 53^{3} + \left(27 a + 34\right)\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 36 + 5\cdot 53 + 42\cdot 53^{2} + 10\cdot 53^{3} + 38\cdot 53^{4} +O\left(53^{ 5 }\right)$
