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:
$r_{ 1 }$ $=$ $ 7 a + 4 + \left(2 a + 3\right)\cdot 11 + 4\cdot 11^{2} + \left(8 a + 8\right)\cdot 11^{3} + 10 a\cdot 11^{4} +O\left(11^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 8 a + 8 + \left(a + 1\right)\cdot 11 + \left(a + 10\right)\cdot 11^{2} + \left(9 a + 10\right)\cdot 11^{3} + \left(5 a + 7\right)\cdot 11^{4} +O\left(11^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 10 a + 10 + \left(8 a + 2\right)\cdot 11 + \left(a + 2\right)\cdot 11^{2} + \left(6 a + 7\right)\cdot 11^{3} + 11^{4} +O\left(11^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 4 a + 10 + \left(8 a + 6\right)\cdot 11 + \left(10 a + 2\right)\cdot 11^{2} + \left(2 a + 7\right)\cdot 11^{3} + 2\cdot 11^{4} +O\left(11^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 3 a + 7 + 9 a\cdot 11 + \left(9 a + 2\right)\cdot 11^{2} + \left(a + 2\right)\cdot 11^{3} + 5 a\cdot 11^{4} +O\left(11^{ 5 }\right)$
$r_{ 6 }$ $=$ $ a + 6 + \left(2 a + 6\right)\cdot 11 + 9 a\cdot 11^{2} + \left(4 a + 8\right)\cdot 11^{3} + \left(10 a + 8\right)\cdot 11^{4} +O\left(11^{ 5 }\right)$
