The label of a Galois orbit of Hilbert cuspforms is given by
(number field label) - (level label) - (orbit label)
separated by dashes. The level ideal for Hilbert modular forms differs from the ideal label used in other parts of the LMFDB, since this data precedes the invention of these labels. The ideal $\mathfrak{N}$ has ideal label of the form $[N, n, \beta]$ where $N=\mathrm{Nm}(\mathfrak{N})$ is the absolute norm, $n$ generates the ideal $\mathfrak{N} \cap \Z$, and $\beta$ is some element such that $\mathfrak{N} = (N, n, \beta)$.
The orbit label is a letter.
