permutation
If you take a set of objects and rearrange the order without taking any away or adding any, that is a permutation of the orginal set of objects. Permutations care about order where combinations do not. If you have n objects there are n! possible permutations of them.
Permutation Example Dijkstra Algorithm Books Links

Permutation Example

For example, the 3! = 6 permutations of three objects a, b and c are:
a b c
a c b
b a c
b c a
c a b
c b a

Dijkstra Algorithm

For code to generate them all read up on the Dijkstra algorithm. Here is an implemenation of the Dijkstra algorithm for permutations and also a combinations algorithm: view
