Self dual: | no |
Analytic conductor: | \(6.13251087523\) |
Analytic rank: | \(0\) |
Dimension: | \(2048\) |
Relative dimension: | \(64\) over \(\Q(\zeta_{64})\) |
Twist minimal: | yes |
Sato-Tate group: | $\mathrm{SU}(2)[C_{64}]$ |
$q$-expansion
The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.
