Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 3 + 15\cdot 31 + 27\cdot 31^{2} + 24\cdot 31^{3} + 16\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 4 + 21\cdot 31^{2} + 18\cdot 31^{3} + 3\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 27 + 30\cdot 31 + 9\cdot 31^{2} + 12\cdot 31^{3} + 27\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 28 + 15\cdot 31 + 3\cdot 31^{2} + 6\cdot 31^{3} + 14\cdot 31^{4} +O\left(31^{ 5 }\right)$
