    Permutations and Combinations

    Hi
    does anyone know of any link that can help me brush up on my permutation and combination rules?
    Even though there are ways of doing the problems for the gmat but going through the selection of each element and then reducing the total pool i felt it will be helpful for everyone if someone could share a link which defines the basics of when to use what i.e. permutation or combination.

    Cheers
