libghc-permutation-prof 0.5.0.5-1build1 (i386 binary) in ubuntu bionic

 This library includes data types for storing permutations and
 combinations. It implements pure and impure types, the latter of
 which can be modified in-place. The library uses aggressive
 inlining and MutableByteArray#s internally, so it is very
 efficient.
 .
 The main utility of the library is converting between the linear
 representation of a permutation and a sequence of swaps. This
 allows, for instance, applying a permutation or its inverse
 to an array with O(1) memory use.
 .
 Much of the interface for the library is based on the permutation
 and combination functions in the GNU Scientific Library (GSL).
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
