``permutation`` provides a ``Permutation`` class for representing `permutations
`_ of finitely many positive
integers in Python.  Supported operations & properties include inverses, (group
theoretic) order, parity, composition/multiplication, cycle decomposition,
cycle notation, word representation, Lehmer codes, and, of course, use as a
callable on integers.


Installation
============
``permutation`` requires Python 3.8 or higher.  Just use `pip
`_ for Python 3 (You have pip, right?) to install::

    python3 -m pip install permutation


Examples
========

>>> from permutation import Permutation
>>> p = Permutation(2, 1, 4, 5, 3)
>>> p(1)
2
>>> p(3)
4
>>> p(42)
42
>>> p.to_cycles()
[(1, 2), (3, 4, 5)]
>>> print(p)
(1 2)(3 4 5)
>>> print(p.inverse())
(1 2)(3 5 4)
>>> p.degree
5
>>> p.order
6
>>> p.is_even
False
>>> p.lehmer(5)
27
>>> q = Permutation.cycle(1,2,3)
>>> print(p * q)
(2 4 5 3)
>>> print(q * p)
(1 3 4 5)
>>> for p in Permutation.group(3):
...     print(p)
