I make this post in order to clarify the meaning of permutations.
Let's take a word as an example.
For e.g. , the word VAP
The word VAP can be arranged in six ways,
1.VAP 2.AVP
3.PAV 4.PVA
5.VPA 6.APV
The word VAP has six possible arrangements, each unique from the other, and such has 6 permutations.
Hail Ma'am Vapula !
Hail Sir Satan !
