Narcissistic-Type Selfie Numbers with Division

This work brings extensions of narcissistic numbers in different situations. Extensions are made for positive and negative coefficients, fixed and flexible powers. The idea is extended for narcissistic numbers with division. Here also different situations are considered, such as, positive and negative coefficients, fixed and flexible powers. Comparison with previous known numbers are also given. … Continue reading Narcissistic-Type Selfie Numbers with Division

Semi-Selfie Numbers

Author studied many ways of writing selfie numbers, sometimes known by wild narcissistic numbers. There are numbers very much near to selfie-number, but are not complete selfie numbers. Let us write these types of numbers, as semi-selfie numbers, where numbers are written in terms of expressions with positive and negative signs having same digits on … Continue reading Semi-Selfie Numbers

Factorial-Power Selfie Expressions

This work brings numbers in such a way that both sides of the expressions are with same digits. 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. Many ways of these types of expressions are studied. For distinct and … Continue reading Factorial-Power Selfie Expressions

Selfie Numbers and Binomial Coefficients

During past years,¬†author studied different types of "selfie numbers", with extra operations as, factorial, square-root, Fibonacci sequence values, etc. This paper brings "selfie numbers" in terms of "binomial coefficients". This has been done in digit's order, reverse order of digits and in both ways. The results are limited¬†to five digits. See below some examples:   … Continue reading Selfie Numbers and Binomial Coefficients
