Permutations


By the permutations of the letters abc it means all of their possible arrangements:
abc
acb
bac
bca
cab
cba
There are 6 permutations of three different things. As the number of things (letters) increases, their permutations grow astronomically. For example, if twelve different things are permuted, then the number of their permutations is 479,001,600.
