Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 113 }$ to precision 5.
Roots: \[ \begin{aligned} r_{ 1 } &= 40 + 35\cdot 113 + 41\cdot 113^{2} + 79\cdot 113^{3} + 67\cdot 113^{4} +O\left(113^{ 5 }\right) \\ r_{ 2 } &= 94 + 58\cdot 113 + 20\cdot 113^{2} + 65\cdot 113^{3} + 55\cdot 113^{4} +O\left(113^{ 5 }\right) \\ r_{ 3 } &= 96 + 64\cdot 113 + 113^{2} + 99\cdot 113^{3} + 91\cdot 113^{4} +O\left(113^{ 5 }\right) \\ r_{ 4 } &= 110 + 66\cdot 113 + 49\cdot 113^{2} + 95\cdot 113^{3} + 10\cdot 113^{4} +O\left(113^{ 5 }\right) \\ \end{aligned}\]
