Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ \( 4 + 2\cdot 17 + 8\cdot 17^{2} + 7\cdot 17^{3} +O(17^{5})\) Copy content Toggle raw display
$r_{ 2 }$ $=$ \( 8 + 8\cdot 17 + 14\cdot 17^{2} + 4\cdot 17^{3} + 7\cdot 17^{4} +O(17^{5})\) Copy content Toggle raw display
$r_{ 3 }$ $=$ \( 11 + 3\cdot 17 + 11\cdot 17^{2} + 7\cdot 17^{3} + 7\cdot 17^{4} +O(17^{5})\) Copy content Toggle raw display
