Factorial-Power Selfie Expressions

This paper brings numbers in such a way that both sides of the expressions are with same digits and in same order. One side is digits with factorial and another side are with same digits with respective powers. These types of expressions, we call as selfie expressions. Three types of expressions are studied. One when digits involved are distinct, second when there is a repetition of digits but only with positive sign. The third type is with repetition of digits with positive and negative signs. In all the cases the digits follow the same order but not the operations. Operations used are only addition, subtraction and multiplication.
