## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 71 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $43 + 66\cdot 71 + 34\cdot 71^{2} + 71^{3} + 27\cdot 71^{4} +O\left(71^{ 5 }\right)$ $r_{ 2 }$ $=$ $50 + 68\cdot 71 + 69\cdot 71^{2} + 32\cdot 71^{3} + 4\cdot 71^{4} +O\left(71^{ 5 }\right)$ $r_{ 3 }$ $=$ $55 + 14\cdot 71 + 52\cdot 71^{2} + 37\cdot 71^{3} + 13\cdot 71^{4} +O\left(71^{ 5 }\right)$ $r_{ 4 }$ $=$ $66 + 62\cdot 71 + 55\cdot 71^{2} + 69\cdot 71^{3} + 25\cdot 71^{4} +O\left(71^{ 5 }\right)$
