Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 19 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 19 }$: \( x^{2} + 18x + 2 \) Copy content Toggle raw display
Roots:
$r_{ 1 }$ $=$ \( 13 a + 10 + \left(4 a + 10\right)\cdot 19 + \left(17 a + 4\right)\cdot 19^{2} + \left(6 a + 2\right)\cdot 19^{3} + \left(2 a + 7\right)\cdot 19^{4} +O(19^{5})\) Copy content Toggle raw display
