Defining polynomial
| $f(x)$ | $=$ |
\( x^{5} - x^{4} - x^{2} + x + 1 \)
|
The roots of $f$ are computed in an extension of $\Q_{ 71 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 71 }$:
\( x^{2} + 69x + 7 \)
Roots:
| $r_{ 1 }$ | $=$ |
\( 42 a + 34 + \left(31 a + 23\right)\cdot 71 + \left(13 a + 44\right)\cdot 71^{2} + \left(68 a + 53\right)\cdot 71^{3} + \left(39 a + 12\right)\cdot 71^{4} +O(71^{5})\)
