- Permutation is the rearranging in a orderly fashion objects or values. Mathematically it defines an operation which arranges a number of objects i.e. digits in a specific order.

For 3 distinct digits1,2,3 we can apply the permutation group operator to generate 6 distanced 3 digit numbers

- Permutation is the rearranging in a orderly fashion objects or values. Mathematically it defines an operation which arranges a number of objects i.e. digits in a specific order.

- Depending on the number of distinct objects the number of permutation group elements vary.
- For Example,
For the 3 distinct objects we can generate 6 group elements and for 4 distinct objects we can generate 24 group elements

Number of group elements= N!

Where the ! Means N factorial, i.e.,

N! = 1x2x3x4x….x N
