Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 71 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ \( 11 + 43\cdot 71 + 8\cdot 71^{2} + 31\cdot 71^{3} + 60\cdot 71^{4} +O(71^{5})\) Copy content Toggle raw display
$r_{ 2 }$ $=$ \( 17 + 24\cdot 71 + 25\cdot 71^{2} + 54\cdot 71^{4} +O(71^{5})\) Copy content Toggle raw display
