Galois action

Roots of defining polynomial

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