Galois action
Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 23 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 23 }$:
\( x^{2} + 21x + 5 \)
Roots:
$r_{ 1 }$ | $=$ | \( 11 a + 4 + \left(20 a + 9\right)\cdot 23 + \left(19 a + 19\right)\cdot 23^{2} + 5\cdot 23^{3} + \left(20 a + 10\right)\cdot 23^{4} +O(23^{5})\) |
$r_{ 2 }$ | $=$ | \( 17 + 19\cdot 23 + 20\cdot 23^{2} + 17\cdot 23^{3} + 19\cdot 23^{4} +O(23^{5})\) |
$r_{ 3 }$ | $=$ | \( 12 a + 3 + \left(2 a + 16\right)\cdot 23 + \left(3 a + 15\right)\cdot 23^{2} + \left(22 a + 10\right)\cdot 23^{3} + \left(2 a + 3\right)\cdot 23^{4} +O(23^{5})\) |
$r_{ 4 }$ | $=$ | \( 10 a + 8 + \left(20 a + 19\right)\cdot 23 + \left(19 a + 10\right)\cdot 23^{2} + \left(4 a + 16\right)\cdot 23^{3} + \left(13 a + 16\right)\cdot 23^{4} +O(23^{5})\) |
$r_{ 5 }$ | $=$ | \( 13 a + 5 + \left(2 a + 4\right)\cdot 23 + \left(3 a + 7\right)\cdot 23^{2} + \left(18 a + 6\right)\cdot 23^{3} + \left(9 a + 15\right)\cdot 23^{4} +O(23^{5})\) |
$r_{ 6 }$ | $=$ | \( 12 + 18\cdot 23^{2} + 11\cdot 23^{3} + 3\cdot 23^{4} +O(23^{5})\) |
