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 $\mathbb{Q}_{ 11 }$:
\( x^{2} + 7x + 2 \)

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