Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 307 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 33 + 301\cdot 307 + 167\cdot 307^{2} + 178\cdot 307^{3} + 97\cdot 307^{4} +O\left(307^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 46 + 130\cdot 307 + 227\cdot 307^{2} + 258\cdot 307^{3} + 175\cdot 307^{4} +O\left(307^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 68 + 41\cdot 307 + 136\cdot 307^{2} + 217\cdot 307^{3} + 244\cdot 307^{4} +O\left(307^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 162 + 141\cdot 307 + 82\cdot 307^{2} + 266\cdot 307^{3} + 95\cdot 307^{4} +O\left(307^{ 5 }\right)$
