Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 263 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 263 }$:
\( x^{2} + 261x + 5 \)
Roots:
$r_{ 1 }$ | $=$ | \( 261 + 63\cdot 263 + 35\cdot 263^{2} + 254\cdot 263^{3} + 54\cdot 263^{4} +O(263^{5})\) |
$r_{ 2 }$ | $=$ | \( 228 a + 251 + \left(258 a + 231\right)\cdot 263 + \left(61 a + 97\right)\cdot 263^{2} + \left(184 a + 242\right)\cdot 263^{3} + \left(15 a + 215\right)\cdot 263^{4} +O(263^{5})\) |
$r_{ 3 }$ | $=$ | \( 85 a + 177 + \left(48 a + 161\right)\cdot 263 + \left(5 a + 34\right)\cdot 263^{2} + \left(226 a + 27\right)\cdot 263^{3} + \left(260 a + 223\right)\cdot 263^{4} +O(263^{5})\) |
$r_{ 4 }$ | $=$ | \( 184 + 198\cdot 263 + 69\cdot 263^{2} + 140\cdot 263^{3} +O(263^{5})\) |
$r_{ 5 }$ | $=$ | \( 35 a + 181 + \left(4 a + 258\right)\cdot 263 + \left(201 a + 225\right)\cdot 263^{2} + \left(78 a + 22\right)\cdot 263^{3} + \left(247 a + 63\right)\cdot 263^{4} +O(263^{5})\) |
$r_{ 6 }$ | $=$ | \( 178 a + 84 + \left(214 a + 173\right)\cdot 263 + \left(257 a + 259\right)\cdot 263^{2} + \left(36 a + 210\right)\cdot 263^{3} + \left(2 a + 255\right)\cdot 263^{4} +O(263^{5})\) |
$r_{ 7 }$ | $=$ | \( 178 + 226\cdot 263 + 65\cdot 263^{2} + 154\cdot 263^{3} + 238\cdot 263^{4} +O(263^{5})\) |
