Self dual: | no |
Analytic conductor: | \(1.64491828164\) |
Analytic rank: | \(0\) |
Dimension: | \(128\) |
Relative dimension: | \(4\) over \(\Q(\zeta_{51})\) |
Twist minimal: | yes |
Sato-Tate group: | $\mathrm{SU}(2)[C_{51}]$ |
$q$-expansion
The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.
