Galois action

Roots of defining polynomial

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