Iwasawa invariants
$p$ | 2 | 3 | 5 | 7 | 11 |
---|---|---|---|---|---|
Reduction type | nonsplit | add | nonsplit | add | split |
$\lambda$-invariant(s) | 6 | - | 0 | - | 5 |
$\mu$-invariant(s) | 1 | - | 0 | - | 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 $0$.
