## 21 Mathematical Hightlights for 2021

This short work brings 21 main representations of 2021 in different ways. These representations are of crazy-type, running numbers, single digit, single letter, Triangular, Fibonacci, palindromic-type, prime numbers, embedded, repeated digits, colored patterns, magic squares, etc. For download this work please go to following link: Inder J. Taneja, […]

## Extended Colored Patterns With 2021 On a Board of 9×9

This work is continuation of work on 2021 given at the following link: Inder J. Taneja, Colored Patterns With 2021 On a Board of 9×9, https://inderjtaneja.com/2020/12/26/colored-pattern-with-2021-on-a-board-of-9×9/ In this work we consider the same designs and put them as blocks of 9×9 (for designs) and 81×81 for small squares. The […]

## Block-Wise and Block-Bordered Magic and Bimagic Squares With Magic Sums 21, 21^2 and 2021

We can always write block-wise magic squares of any order except for the orders of type p and 2p, where p is a prime number. On the other hand we can always write bordered magic squares of any order. The aims of this work is to bring both […]
