Passport label (awaiting review)

The label of a passport is of the form $d$T$G$-$\lambda_0\_\lambda_1\_\lambda_\infty$, where $d$T$G$ is the label of the associated transitive group, and the $\lambda_i$ are partitions of $d$, corresponding to the associated triple of conjugacy classes $(C_0, C_1, C_\infty)$ of $S_d$. (Each $\lambda_i$ is written using . as a separator between the parts of the partition.)
