Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 53 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 53 }$: \( x^{2} + 49x + 2 \) Copy content Toggle raw display
Roots:
$r_{ 1 }$ $=$ \( 16 + 36\cdot 53 + 29\cdot 53^{2} + 11\cdot 53^{3} + 11\cdot 53^{4} +O(53^{5})\) Copy content Toggle raw display
$r_{ 2 }$ $=$ \( 19 a + 23 + \left(40 a + 13\right)\cdot 53 + \left(14 a + 30\right)\cdot 53^{2} + \left(47 a + 43\right)\cdot 53^{3} + \left(24 a + 51\right)\cdot 53^{4} +O(53^{5})\) Copy content Toggle raw display
