Taneja1 Abstract This work summarizes author’s previous works on magic squares of order 18. It brings different types of magic square such as block-wise, single-digit bordered, double-digit bordered, cornered, designs, styles, etc. In terms os aspects, we have considered the idea of Pythagorean triples, perfect square sum entries, Latin square distributions, upside-down, mirror-looking, water reflection, algebraic magic squares, etc. 1Formerly, Professor of Mathematics, Universidade Federal de Santa Catarina, Florian´ opolis, SC, Brazil (1978-2012).

Taneja https://inderjtaneja.wordpress.com; https://numbers-magic.com Different Types and Aspects of Magic Squares of Order 18, Zenodo, November 14, 2025, pp. 1-68, https://doi.org/10.5281/zenodo.17613304 1 Introduction In the previous works [19, 20, 21, 22, 23, 24, 25], the author worked with block-wise constructions of magic squares. The work is from the orders 8 to 45. In each case, all the possibilities are considered. These possibilities are based on divisions of magic squares. The magic sums of order nof consecutive numbers from 1 to n2is given by Sn×n:= n×(1 + n2) 2, n ≥3.(1) This formula is applied to all order magic squares. Based on this formula we shall brink blocks for the block-wise magic squares. That is, whenever is possible, we shall try to bring blocks of equal sum magic squares. In some cases, they are magic,semi-magic,pandiagonal, etc. When the question come to bimagic squares, in some cases, we have semi-bimagic squares. On the other hand the idea of bordered magic squares is well explained in the work by H.White [4, 5]. Few results in this direction can be seen in author’s work [26, 27, 28, 29, 30, 31]. In some case, the magic rectangles are also used to write it in different styles. Most of the author’s work on magic squares is summarized below in details according to topic: 1. Digital Fonts: Upside-down and Mirror Looking. 2. Two Digits Universal Magic Squares. 3. Different Digits Magic Squares. 4. Pythagorean Triples Magic Squares. 5. Block-Wise Magic Squares. 6. Selfie and Palindromic Type Magic Squares. 7. Block Bordered Magic Squares. 8. Block-Wise Bordered Magic Squares. 9. Magic Crosses, Letters and Numbers. 10. Cornered Magic Squares. 11. Single-Digit Bordered Magic Squares. 12. Double-Digit Bordered Magic Squares. 13. Multiple-Digit Bordered Magic Squares. 14. Striped Magic Squares. 15. Upside-down and Mirror Looking. 3 Inder J. Taneja https://inderjtaneja.wordpress.com; https://numbers-magic.com Different Types and Aspects of Magic Squares of Order 18, Zenodo, November 14, 2025, pp. 1-68, https://doi.org/10.5281/zenodo.17613304 16. Water reflection Magic Squares. 17. Algebraic Magic Squares. The aim of this work is to write magic squares of order 18 in different ways and styles using the aspects of blocks, bordered,block-bordered and magic rectangles,corner-type,single-digit,double-digit, etc. More details on these works on magic squares can be seen in author’s web-sites: (i) https://numbers-magic.com/?p=668 (ii) https://inderjtaneja.wordpress.com/2019/06/27/publications-magic-squares/ 2 Different Types of Magic Squares According to Equation (1), the magic sum of order 18 is given by S18×18 := 18 ×(1 + 182) 2= 2925. We can write, 18 := 2 ×3×3. This gives the possibility of blocks of orders 3 and 6. Let’s see division of 2925 by 6 and 3: (i)2925 6=975 2=⇒non-equal blocks of order 3; (ii)2925 3= 975 =⇒equal blocks of order 6. Below are few examples of different types of magic squares of order 18. 4 Inder J.
