Numbers represented by their own digits by certain operations are considered as **selfie numbers**. Some times they are called as **wild narcissistic numbers**. There are many ways of representing **selfie numbers**. They can be represented in digit’s order, reverse order of digits, increasing and/or decreasing order of digits, etc. These can be obtained by use of basis operations along with **factorial, square-root, Fibonacci sequence, Triangular numbers, binomial coefficients, S-gonal values, centered polygonal numbers**, etc. In this work, we have written **selfie numbers** by use of **concatenation**, along with **factorial** and **square-root**. The concatenation idea is used in a very simple way. The work is limited up to 5 digits. Work on higher digits shall be dealt elsewhere. Below are some examples and link for download the work.
