The label for an Artin representation takes the form A.B.C.DcE where

  • A is the dimension of the representation
  • B is the conductor of the representation, the format for which is explained below
  • C is the smallest permutation representation for which this representation is a factor. If the degree is small enough, we give the degree d and t-number j in the form dtj; otherwise we use just the degree d.
  • D is an index to distinguish cases where non-Galois conjugate representations have the same dimension, conductor, and smallest permutation representation
  • E is an index for the representation within its Galois conjugates

The conductor is given in factored form with the following encoding. Underscores (_) are to be interpreted as multiplication signs and "e" indicates exponentiation. So, 2e3_59 converts to $2^3\cdot 59$.
