Permutation
Summary
A permutation of a set is a rearrangement of its elements, that is, a bijection from the set to itself. Permutations are the basic objects of enumerative combinatorics and of the theory of symmetric groups. The node permutation gives the precise definition.
What this node needs for W2
- edge instance_of in: at least two examples (0 of 2)
- edge not_instance_of in: at least one non-example (0 of 1)
- edge specializes both: the more general notions and the special cases (0 of 1)
The writing levels say how complete the text of a node is. They do not measure its truth.
