Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 41 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 7 + 8\cdot 41 + 6\cdot 41^{2} + 6\cdot 41^{3} + 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 19 + 2\cdot 41 + 17\cdot 41^{2} + 33\cdot 41^{3} + 13\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 27 + 8\cdot 41 + 20\cdot 41^{2} + 32\cdot 41^{3} + 14\cdot 41^{4} +O\left(41^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 29 + 21\cdot 41 + 38\cdot 41^{2} + 9\cdot 41^{3} + 11\cdot 41^{4} +O\left(41^{ 5 }\right)$
