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. Below are examples examples […]

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 […]

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 […]
