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 both … Continue reading Patterns in Semi-Selfie Numbers

## Number Patterns: Single Letter Representations

This work brings representations of palindromic and number patterns in terms of single letter ”a”. Some examples of prime number patterns are also considered. Different classifications of palindromic patterns are considered, such as, palindromic decompositions, double symmetric patterns, number pattern decompositions, etc. Numbers patterns with power are also studied. Below are some examples and links … Continue reading Number Patterns: Single Letter Representations

## Fixed Length Multiple Choice Patterns in Prime Numbers

Recently, author worked with patterns in prime numbers in such a way that they can be extended by inserting digits in repeated ways, and still remains prime numbers. This kind of patterns goes up to fixed length. These types of prime numbers, we call "patterns in prime numbers". There are prime patterns written in diferente … Continue reading Fixed Length Multiple Choice Patterns in Prime Numbers

## Patterns in Prime Numbers: Fixed Digits Repetitions

In this paper, we shall work with prime numbers in such a way that they can be extended by inserting digits in repeated ways, and still it continues prime numbers. These types of prime numbers called "Patterns in Prime Numbers". The repetition of digits are with one, two, three, four, five and six digits. This … Continue reading Patterns in Prime Numbers: Fixed Digits Repetitions
