WebOct 4, 2024 · Most of the PBI methods, e.g. [4, 13, 17], use only a fixed-length prefix of the permutations in order to represent or compare objects. This choice is based on the intuition that the most relevant information in the permutation is present in its very first elements, i.e. the identifiers of the closest pivots.

WebMar 5, 2024 · We will usually denote permutations by Greek letters such as π (pi), σ (sigma), and τ (tau). The set of all permutations of n elements is denoted by Sn and is typically referred to as the symmetric group of degree n. (In particular, the set Sn forms a group under function composition as discussed in Section 8.1.2).
