Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 53 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 4 + 38\cdot 53 + 27\cdot 53^{2} + 42\cdot 53^{3} + 36\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 17 + 32\cdot 53 + 46\cdot 53^{2} + 9\cdot 53^{3} + 15\cdot 53^{4} +O\left(53^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 32 + 35\cdot 53 + 31\cdot 53^{2} + 53^{4} +O\left(53^{ 5 }\right)$
