What is the most mysterious number?

Therefore the number 6174 is the only number unchanged by Kaprekar’s operation — our mysterious number is unique. The number 495 is the unique kernel for the operation on three digit numbers, and all three digit numbers reach 495 using the operation. Why don’t you check it yourself?
