Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 419 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 15 + 96\cdot 419 + 77\cdot 419^{2} + 191\cdot 419^{3} + 315\cdot 419^{4} +O\left(419^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 191 + 256\cdot 419 + 241\cdot 419^{2} + 9\cdot 419^{3} + 107\cdot 419^{4} +O\left(419^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 293 + 207\cdot 419 + 203\cdot 419^{2} + 312\cdot 419^{3} + 409\cdot 419^{4} +O\left(419^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 341 + 277\cdot 419 + 315\cdot 419^{2} + 324\cdot 419^{3} + 5\cdot 419^{4} +O\left(419^{ 5 }\right)$
