Defining polynomial
| $f(x)$ | $=$ |
\( x^{5} - 2x^{4} + 2x^{3} - 2x + 2 \)
|
The roots of $f$ are computed in an extension of $\Q_{ 37 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 37 }$:
\( x^{2} + 33x + 2 \)
Roots:
| $r_{ 1 }$ | $=$ |
\( 33 a + 11 + \left(21 a + 3\right)\cdot 37 + \left(26 a + 4\right)\cdot 37^{2} + \left(36 a + 5\right)\cdot 37^{3} + \left(24 a + 33\right)\cdot 37^{4} +O(37^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 16 + 34\cdot 37 + 36\cdot 37^{2} + 27\cdot 37^{3} + 31\cdot 37^{4} +O(37^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 35 + 32\cdot 37 + 34\cdot 37^{2} + 17\cdot 37^{3} +O(37^{5})\)
|

|
| $r_{ 5 }$ | $=$ |
