## Miraculous Constant 8181

**This work is a special birthday gift to my sweetheart, my wife Jyoti Satpute**

1) Place the largest digit at the 1000’s place and the smallest digit at the 100’s place.

Out of the remaining 2 digits:

2) Place the largest digit at the 10’s place and the smallest digit at the unit place.

Example: Let’s say the input number is 8492. Let’s form the Zigzag number from this.

1) The highest digit of the given number 8492 is 9 and the smallest digit is 2. So, the 1000’s placed digit of the Zigzag number will be 9, and the 100’s placed digit will be 2.

**∀ a, b, c, d ∈**

**W, a set of whole numbers,**then the Zigzag number will be 1000a + 100d + 10b + c and its reverse number is 1000c + 100b + 10d + a. At least one digit out of a, b, c, or d must be different from others.

Repeat this process called iteration until you get 8181 (Miraculous constant).

**Introduction**

**Method**

**Figure-1**

*The number of iterations for 8492 to get the Miraculous Constant 8181 is 8.*
