Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 19 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 19 }$: $ x^{2} + 18 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 16 a + 2 + \left(5 a + 8\right)\cdot 19 + \left(8 a + 8\right)\cdot 19^{2} + \left(18 a + 1\right)\cdot 19^{3} + \left(10 a + 12\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 3 a + 18 + \left(13 a + 16\right)\cdot 19 + \left(10 a + 10\right)\cdot 19^{2} + 11\cdot 19^{3} + \left(8 a + 4\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 14 + 13\cdot 19 + 17\cdot 19^{2} + 14\cdot 19^{3} + 15\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 5 a + 9 + \left(a + 1\right)\cdot 19 + \left(12 a + 14\right)\cdot 19^{2} + \left(16 a + 2\right)\cdot 19^{3} + \left(a + 10\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 14 a + 14 + \left(17 a + 16\right)\cdot 19 + \left(6 a + 5\right)\cdot 19^{2} + \left(2 a + 7\right)\cdot 19^{3} + \left(17 a + 14\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$
