Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 8 + 12\cdot 17 + 2\cdot 17^{2} + 4\cdot 17^{3} + 11\cdot 17^{4} +O(17^{5})\) |
$r_{ 2 }$ | $=$ | \( 10 + 4\cdot 17 + 14\cdot 17^{2} + 12\cdot 17^{3} + 5\cdot 17^{4} +O(17^{5})\) |
