Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 109 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 20 + 54\cdot 109 + 101\cdot 109^{2} + 57\cdot 109^{3} + 40\cdot 109^{4} +O\left(109^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 56 + 40\cdot 109 + 25\cdot 109^{2} + 85\cdot 109^{4} +O\left(109^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 58 + 38\cdot 109 + 65\cdot 109^{2} + 90\cdot 109^{3} + 83\cdot 109^{4} +O\left(109^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 84 + 84\cdot 109 + 25\cdot 109^{2} + 69\cdot 109^{3} + 8\cdot 109^{4} +O\left(109^{ 5 }\right)$
