## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 53 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $30 + 31\cdot 53 + 8\cdot 53^{2} + 7\cdot 53^{3} + 14\cdot 53^{4} +O\left(53^{ 5 }\right)$ $r_{ 2 }$ $=$ $35 + 51\cdot 53 + 41\cdot 53^{2} + 4\cdot 53^{3} + 14\cdot 53^{4} +O\left(53^{ 5 }\right)$ $r_{ 3 }$ $=$ $47 + 49\cdot 53 + 21\cdot 53^{2} + 9\cdot 53^{3} + 2\cdot 53^{4} +O\left(53^{ 5 }\right)$ $r_{ 4 }$ $=$ $48 + 25\cdot 53 + 33\cdot 53^{2} + 31\cdot 53^{3} + 22\cdot 53^{4} +O\left(53^{ 5 }\right)$
