Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$ except those listed in the table below.

Iwasawa invariants
| $p$ | 2 | 3 | 5 | 7 |
|---|---|---|---|---|
| Reduction type | split | add | nonsplit | add |
| $\lambda$-invariant(s) | 5 | - | 0 | - |
| $\mu$-invariant(s) | 1 | - | 0 | - |
All Iwasawa $\lambda$ and $\mu$-invariants for primes $p\ge 5$ of good reduction are zero.
An entry - indicates that the invariants are not computed because the reduction is additive.
$p$-adic regulators
All $p$-adic regulators are identically $1$ since the rank is $0$.
