![]() ![]() 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. For lazy or interruptible evaluation, see the second example below. permutation provides a Permutation class for representing permutations of finitely many positive integers in Python. Permutations with repetitions, using strict evaluation, generating the entire set (where system constraints permit) with some degree of efficiency.

See Also: The number of samples of size k from n objects. This case is a good example of where it is not required to store all the intermediate permutations. This sequence will have elements, unless the program decides to terminate early.ĭo not store all the intermediate values of the sequence, rather generate them as required, and pass the intermediate result to a deciding routine for combinations selection and/or early generator termination.įor example: When "cracking" a "combination" lock a sequence is required, but the sequence is terminated once a successful "combination" is found. Generate a sequence of permutations of n elements drawn from choice of k values. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page. Permutations with repetitions is a draft programming task. ![]()
