Self dual: | no |
Analytic conductor: | \(10.3814980721\) |
Analytic rank: | \(0\) |
Dimension: | \(1008\) |
Relative dimension: | \(84\) over \(\Q(\zeta_{42})\) |
Twist minimal: | yes |
Sato-Tate group: | $\mathrm{SU}(2)[C_{42}]$ |
$q$-expansion
The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.
