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: \begin{aligned} r_{ 1 } &= 2 a + 1 + \left(a + 6\right)\cdot 7 + \left(5 a + 5\right)\cdot 7^{2} + \left(a + 5\right)\cdot 7^{3} + \left(5 a + 4\right)\cdot 7^{4} +O\left(7^{ 5 }\right) \\ r_{ 2 } &= 6 + 5\cdot 7 + 4\cdot 7^{2} + 7^{3} + 6\cdot 7^{4} +O\left(7^{ 5 }\right) \\ r_{ 3 } &= 6 a + 3 + \left(3 a + 6\right)\cdot 7 + \left(a + 4\right)\cdot 7^{2} + 4 a\cdot 7^{3} + \left(4 a + 4\right)\cdot 7^{4} +O\left(7^{ 5 }\right) \\ r_{ 4 } &= 5 a + 3 + \left(5 a + 5\right)\cdot 7 + \left(a + 2\right)\cdot 7^{2} + \left(5 a + 2\right)\cdot 7^{3} + \left(a + 1\right)\cdot 7^{4} +O\left(7^{ 5 }\right) \\ r_{ 5 } &= a + 2 + \left(3 a + 4\right)\cdot 7 + \left(5 a + 2\right)\cdot 7^{2} + \left(2 a + 3\right)\cdot 7^{3} + \left(2 a + 4\right)\cdot 7^{4} +O\left(7^{ 5 }\right) \\ \end{aligned}
