Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 23 }$ to precision 6.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 23 }$: $ x^{2} + 21 x + 5 $
Roots:
$r_{ 1 }$ $=$ $ 6\cdot 23 + 19\cdot 23^{2} + 7\cdot 23^{3} + 3\cdot 23^{4} +O\left(23^{ 6 }\right)$
$r_{ 2 }$ $=$ $ 2 a + 10 + \left(20 a + 12\right)\cdot 23 + \left(2 a + 20\right)\cdot 23^{2} + \left(18 a + 13\right)\cdot 23^{3} + \left(11 a + 18\right)\cdot 23^{4} + \left(19 a + 20\right)\cdot 23^{5} +O\left(23^{ 6 }\right)$
$r_{ 3 }$ $=$ $ 13 a + 7 + \left(17 a + 11\right)\cdot 23 + \left(12 a + 19\right)\cdot 23^{2} + \left(6 a + 14\right)\cdot 23^{3} + \left(18 a + 22\right)\cdot 23^{4} + \left(17 a + 17\right)\cdot 23^{5} +O\left(23^{ 6 }\right)$
$r_{ 4 }$ $=$ $ 21 a + 14 + \left(2 a + 4\right)\cdot 23 + \left(20 a + 6\right)\cdot 23^{2} + \left(4 a + 1\right)\cdot 23^{3} + \left(11 a + 1\right)\cdot 23^{4} + \left(3 a + 2\right)\cdot 23^{5} +O\left(23^{ 6 }\right)$
$r_{ 5 }$ $=$ $ 10 a + 10 + \left(5 a + 10\right)\cdot 23 + \left(10 a + 4\right)\cdot 23^{2} + \left(16 a + 15\right)\cdot 23^{3} + \left(4 a + 6\right)\cdot 23^{4} + \left(5 a + 12\right)\cdot 23^{5} +O\left(23^{ 6 }\right)$
$r_{ 6 }$ $=$ $ 7 + 23 + 22\cdot 23^{2} + 15\cdot 23^{3} + 16\cdot 23^{4} + 15\cdot 23^{5} +O\left(23^{ 6 }\right)$
