Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 199 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 60 + 70\cdot 199 + 65\cdot 199^{2} + 44\cdot 199^{3} + 154\cdot 199^{4} +O\left(199^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 81 + 144\cdot 199 + 144\cdot 199^{2} + 151\cdot 199^{3} + 182\cdot 199^{4} +O\left(199^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 116 + 47\cdot 199 + 164\cdot 199^{2} + 62\cdot 199^{3} + 196\cdot 199^{4} +O\left(199^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 142 + 135\cdot 199 + 23\cdot 199^{2} + 139\cdot 199^{3} + 63\cdot 199^{4} +O\left(199^{ 5 }\right)$
