Welcome to part 7, where the magic squares are 7×7. I don’t know if there is any numerological significance to that, but it wasn’t intended. Although, if someone wanted to make something of it, 7 was the number of known planets in medieval times, as well as the number of known elements, and […]

I have met with some disappointment as to how a methodology for creating a 4×4 square should pan out, and instead I have come up with many different algorithms, each resulting in its own small sets of magic squares, but had stumbled upon a set of squares with similar “hypermagical” properties which I […]

I was experimenting with Danny Dawson’s 4×4 magic square script, and began to consider writing my own script. But I just thought I would do a few runs for my own research. I wanted to thank Mr. Dawson for his fine work which I am obviously gaining knowledge from, but his comments page […]

How to Make a Random Square
I have noticed that it has been difficult to elucidate a method for systematically creating evenordered magic squares of any but the most basic kind. I don’t know why this is, since the art has been alive in Europe for at least 600 years, and probably longer […]

Notice that to show the rules for making these kind of magic squares, I used only oddordered square matrices as examples. What about matrices of even numbers of rows and columns? The rules for these vary.
This is a small part of a 1514 engraving by Albrecht Durer, called Melancholia. The author […]

Last time I introduced the idea of magic squares. I promised I would show you how to make one. In this post, I will begin by discussing “trivial” squares, or squares made by simple rules of following diagonals and wrapping.
When I say a square is “magic”, I mean that all rows, columns, […]

Introduction
ONE OF THE few things you see on the web these days is how to do a really good magic square. There are many websites that tell you about how spiralling arrangements of sequential numbers on a square matrix is magic, but for me, that’s dull. You are limited to doing […]
