Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 79 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 79 }$:
\( x^{2} + 78x + 3 \)
Roots:
$r_{ 1 }$ | $=$ |
\( 4 a + 17 + \left(61 a + 42\right)\cdot 79 + \left(77 a + 70\right)\cdot 79^{2} + \left(77 a + 52\right)\cdot 79^{3} + \left(39 a + 45\right)\cdot 79^{4} +O(79^{5})\)
$r_{ 2 }$ |
$=$ |
\( 23 a + 5 + \left(62 a + 4\right)\cdot 79 + 43\cdot 79^{2} + \left(9 a + 51\right)\cdot 79^{3} + \left(61 a + 18\right)\cdot 79^{4} +O(79^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 16 a + 31 + 77\cdot 79 + \left(46 a + 28\right)\cdot 79^{2} + \left(46 a + 8\right)\cdot 79^{3} + \left(51 a + 20\right)\cdot 79^{4} +O(79^{5})\)
