You can put this solution on YOUR website! A permutation is when order matters (eg: ABC is different from CBA)
A combination is where order does not matter (eg: ABC is now the same as CBA, all we care about is that the 3 are in the same group)
Answer by tommyt3rd(5050)  (Show Source):
You can put this solution on YOUR website! Note that permutation is another word for arrangement. A combination is an arrangement where order does not matter, but for a permutation it does. For example
for combinations
{a,b,c}={a,c,b}={c,b,a}=...
because they all contain an a, b and a c
but if their order is important then all of those lists are distinct arrangements
in fact there are six such arrangements of a,b,c:
abc
acd
bac
bca
cab
cba
hope this helps
