Iwasawa invariants
| $p$ | 2 | 3 | 5 | 7 | 11 | 13 |
|---|---|---|---|---|---|---|
| Reduction type | nonsplit | split | ord | nonsplit | add | split |
| $\lambda$-invariant(s) | 2 | 1 | 2 | 0 | - | 1 |
| $\mu$-invariant(s) | 0 | 0 | 0 | 0 | - | 0 |
All Iwasawa $\lambda$ and $\mu$-invariants for primes $p\ge 7$ 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 $0$.
