## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 293 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $24 + 26\cdot 293 + 236\cdot 293^{2} + 221\cdot 293^{3} + 262\cdot 293^{4} +O\left(293^{ 5 }\right)$ $r_{ 2 }$ $=$ $36 + 18\cdot 293 + 2\cdot 293^{2} + 248\cdot 293^{3} + 85\cdot 293^{4} +O\left(293^{ 5 }\right)$ $r_{ 3 }$ $=$ $64 + 279\cdot 293 + 85\cdot 293^{2} + 42\cdot 293^{3} + 140\cdot 293^{4} +O\left(293^{ 5 }\right)$ $r_{ 4 }$ $=$ $170 + 262\cdot 293 + 261\cdot 293^{2} + 73\cdot 293^{3} + 97\cdot 293^{4} +O\left(293^{ 5 }\right)$
