Self dual: | yes |
Analytic conductor: | \(119.360863942\) |
Analytic rank: | \(0\) |
Dimension: | \(56\) |
Twist minimal: | no (minimal twist has level 119) |
Fricke sign: | \(1\) |
Sato-Tate group: | $\mathrm{SU}(2)$ |
$q$-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.
