sage: f = N[0] # Warning: the index may be different

Self dual: | no |
Analytic conductor: | \(14.2194603114\) |
Analytic rank: | \(0\) |
Dimension: | \(120\) |
Relative dimension: | \(60\) over \(\Q(\zeta_{3})\) |
Twist minimal: | yes |
Sato-Tate group: | $\mathrm{SU}(2)[C_{3}]$ |
$q$-expansion
The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.
Embeddings
For each embedding \(\iota_m\) of the coefficient field, the values \(\iota_m(a_n)\) are shown below.
