Galois action

Roots of defining polynomial

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