Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 6 + 17\cdot 31 + 14\cdot 31^{2} + 18\cdot 31^{3} + 26\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 18 + 29\cdot 31 + 4\cdot 31^{2} + 10\cdot 31^{3} + 26\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 19 + 19\cdot 31 + 29\cdot 31^{2} + 14\cdot 31^{3} + 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 21 + 26\cdot 31 + 12\cdot 31^{2} + 18\cdot 31^{3} + 7\cdot 31^{4} +O\left(31^{ 5 }\right)$
