## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 29 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $2 + 10\cdot 29 + 18\cdot 29^{2} + 16\cdot 29^{3} + 10\cdot 29^{4} +O\left(29^{ 5 }\right)$ $r_{ 2 }$ $=$ $5 + 22\cdot 29 + 6\cdot 29^{2} + 7\cdot 29^{3} + 25\cdot 29^{4} +O\left(29^{ 5 }\right)$ $r_{ 3 }$ $=$ $24 + 6\cdot 29 + 22\cdot 29^{2} + 21\cdot 29^{3} + 3\cdot 29^{4} +O\left(29^{ 5 }\right)$ $r_{ 4 }$ $=$ $27 + 18\cdot 29 + 10\cdot 29^{2} + 12\cdot 29^{3} + 18\cdot 29^{4} +O\left(29^{ 5 }\right)$
