Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 37 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 7 + 20\cdot 37 + 7\cdot 37^{2} + 8\cdot 37^{3} + 15\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 12 + 6\cdot 37 + 26\cdot 37^{2} + 17\cdot 37^{3} + 2\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 28 + 28\cdot 37 + 34\cdot 37^{2} + 11\cdot 37^{3} + 17\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 31 + 25\cdot 37 + 11\cdot 37^{3} + 33\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 34 + 29\cdot 37 + 4\cdot 37^{2} + 25\cdot 37^{3} + 5\cdot 37^{4} +O\left(37^{ 5 }\right)$
