## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 73 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $13 + 42\cdot 73 + 42\cdot 73^{2} + 29\cdot 73^{3} + 73^{4} +O\left(73^{ 5 }\right)$ $r_{ 2 }$ $=$ $26 + 25\cdot 73 + 35\cdot 73^{2} + 14\cdot 73^{3} + 15\cdot 73^{4} +O\left(73^{ 5 }\right)$ $r_{ 3 }$ $=$ $48 + 47\cdot 73 + 37\cdot 73^{2} + 58\cdot 73^{3} + 57\cdot 73^{4} +O\left(73^{ 5 }\right)$ $r_{ 4 }$ $=$ $61 + 30\cdot 73 + 30\cdot 73^{2} + 43\cdot 73^{3} + 71\cdot 73^{4} +O\left(73^{ 5 }\right)$
