Galois action

Roots of defining polynomial

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