Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 97 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 29 + 56\cdot 97 + 66\cdot 97^{2} + 85\cdot 97^{3} + 55\cdot 97^{4} +O\left(97^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 34 + 76\cdot 97 + 30\cdot 97^{2} + 77\cdot 97^{3} + 51\cdot 97^{4} +O\left(97^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 50 + 19\cdot 97 + 40\cdot 97^{2} + 85\cdot 97^{3} + 53\cdot 97^{4} +O\left(97^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 81 + 41\cdot 97 + 56\cdot 97^{2} + 42\cdot 97^{3} + 32\cdot 97^{4} +O\left(97^{ 5 }\right)$
