Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 11 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 11 }$: $ x^{2} + 7 x + 2 $
Roots: \[ \begin{aligned} r_{ 1 } &= 4 a + 5 + 3\cdot 11 + \left(10 a + 7\right)\cdot 11^{2} + \left(8 a + 10\right)\cdot 11^{3} + \left(8 a + 7\right)\cdot 11^{4} +O\left(11^{ 5 }\right) \\ r_{ 2 } &= 7 a + 10 + 10 a\cdot 11 + 3\cdot 11^{2} + \left(2 a + 3\right)\cdot 11^{3} + \left(2 a + 1\right)\cdot 11^{4} +O\left(11^{ 5 }\right) \\ r_{ 3 } &= a + 5 + 5\cdot 11 + \left(3 a + 8\right)\cdot 11^{2} + \left(6 a + 6\right)\cdot 11^{3} + \left(10 a + 8\right)\cdot 11^{4} +O\left(11^{ 5 }\right) \\ r_{ 4 } &= 6 + 7\cdot 11 + 4\cdot 11^{2} + 5\cdot 11^{3} + 3\cdot 11^{4} +O\left(11^{ 5 }\right) \\ r_{ 5 } &= 10 a + 9 + \left(10 a + 4\right)\cdot 11 + \left(7 a + 9\right)\cdot 11^{2} + \left(4 a + 6\right)\cdot 11^{3} +O\left(11^{ 5 }\right) \\ \end{aligned}\]
