Two related ten-in one

This order-8 magic square contains four order-4 magic squares in the quadrants and one order-4 in the center.
It contains four more order-4 magic squares starting with the top left hand corner at 24, 59, 27 and 20 (outlined in blue).

S4 = 130      S8 = 260

All ten of these magic squares have the additional feature that each of the four bent diagonals also sum correctly. Two of these bent diagonals in the top left hand order-4 are 1 + 64 + 3 + 62 and 1 + 64 + 17 + 48.
An order-8 bent diagonal is 44 + 21 + 7 + 58 + 37 + 28 + 10 + 55.

Figure 12a from Inlaid Magic Squares & Cubes, page 18


This order-8 magic square is pandiagonal. The four order-4 magic squares in the quadrants are also pandiagonal.

The order-4 in the center and the four order-4 outlined in blue are regular magic squares.

Order-15 Composite

This order-15 magic square consists of 9 order-5 magic squares, each with an order-3 inlaid diamond magic square.

As is common with composite magic squares, the magic sums of the order-5 squares themselves form an order-3 magic square with the constant 1695.
The constants of the order-3 magic diamonds form an order-3 magic square with the constant 1017.

Order-3 Magic Cube

9 rows, such as 1 - 17 - 24, sum to 42.
9 columns, such as 1 - 15 - 26, sum to 42.
9 Pillars, such as 1 - 23 - 18, sum to 42.
4 triagonals, such as 26 - 14 - 2 sum to 42.

Some of the squares may have diagonals summing to 42, but this is not a requirement. In fact, order-8 is the smallest cube for which it is possible for all the diagonals to sum correctly.

What is required is that the 4 triagonals or 3-agonals, such as 1 - 14 - 27 sum to 42.

There are 4 different basic pure (using numbers 1 to 27) magic cubes. Each of these have 48 equivalents due to rotations and/or reflections.

Just as the one order-3 magic square is associated, so also are the four order-3 magic cubes. Because they are associated, all are also self-similar. That is, when each number is subtracted from 28 the result is a reflection of itself. See my Self-similar Magic Squares.

From The Magic Square Course, page 329.

Pan-3-agonal magic cube

16 rows sum to 130
16 columns sum to 130
16 pillars sum to 130
Four 3-dimensional diagonals sum to 130.
All broken 3-agonals parallel to the 4 main triagonals also sum to 130.
This is the equivalent to the pandiagonal Magic Square.

Because it is pandiagonal, any face may be moved to the opposite side, thus creating a new pan-3-agonal magic cube.
The numbers circled in red show one of the 4 main triagonals.
In an order-4 cube it is impossible for all the diagonals parallel to the faces to be magic.

John Hendricks coined the term pan-3-agonal for the broken space 3- agonals.
There are 7680 pan-3-agonal magic cubes of order-4. The total number of Order-4 magic cubes is not known.

From The Magic Square Course, page 384.
This also appeared in The Journal of Recreational Mathematics, 5(1) p. 51-52.

Order-3 Magic Tesseract

This order-3 hypercube of four dimensions is shown in two dimensions using lines to depict the outer dimensions only. The colored numbers here show the middle cube in the horizontal plane. There are three cubes also in each of the other three planes.

27 rows, such as 50 - 12 - 61, sum to 123.
27 columns, such as 50 - 72 - 1, sum to 123.
27 pillars, such as 50 - 64 - 9, sum to 123.
27 files, such as 50 - 16 - 57, sum to 123.
8 quadragonals, such as 1 - 41 - 81 sum to 123.

Some of the squares may have diagonals summing to 123 and some of the cubes may have triagonals summing to 123. These are not requirements of a magic tesseract just as a magic cube is not required to have the planar square diagonals summing to 42.
What is required is that the 8 quadragonals or 4-agonals, such as 50 - 41 - 32 sum to 123.

There are 58 different basic pure (using numbers 1 to 81) magic tesseracts. Each of these have 384 equivalents due to rotations and/or reflections.

Just as the one order-3 magic square and the four order-3 magic cubes are associated, so also are the 58 order-3 magic tesseracts. Because they are associated, all are also self-similar. That is, when each number is subtracted from 82 (i.e. complimented), the result is a reflection of itself and is one of the 384 aspects of this figure.  See my Self-similar Magic Squares.

From The Magic Square Course, page 470-491 (which shows all 58 order-3).

Order-8 Inlaid Magic Cube

Here is the shell for an order-8 magic cube with an inlaid order-4  magic cube.
Each of the six windows shown holds two order-4 pandiagonal magic squares.

The inner order-4 cube is pantriagonal meaning that all broken triagonal pairs sum correctly to 1026.

The order-8 cube uses the numbers from 1 to 83 and has the magic sum of 2052.

Note that it is not a requirement that planar diagonals sum correctly for a cube to be considered magic, although it is possible for an order-8 (the smallest order cube) to have this feature .

The author reasons that there are 2,717,908,992 variations of this one cube, obtainable by rotations, reflections and transformations of the components.

  Following are listed the individual layers of the cube. Note that in most cases they are only semi-magic (the planar diagonals are not required to sum correctly for the cube to be considered magic).

From the above eight horizontal planes, the 16 vertical planes and the four triagonals can be assembled.

Inlaid Magic Tesseract

# 308 - 151 St. Andrews St.,
Victoria, B.C., V8V 2M9

15 October, 1999


                         Minor Announcement

Discovered during the spring of 1999, was a new method of making magic squares of order 2k. An example shown top left is a tenth-order magic square which sums 505 in rows columns and diagonals. In the second quadrant, you will find inlaid a 5th-order magic square which sums 315. Inlaid squares and various methods abound, so this simply adds another method into the system.


The technique mentioned above, can be extended to three and four-dimensional space and higher. A magic tesseract of order six, with an Inlaid magic tesseract of order three has been made. It contains the numbers from 1 to 1296 and sums 3,891 in the required 872 different ways. This is the world’s first magic tesseract of order six.

The inlaid magic tesseract of order three sums 1,824, in the required 116 different ways. This becomes the world’s first inlaid magic tesseract.

The new method for magic squares will be taken into account in the upcoming Second Edition of Inlaid Magic Squares and Cubes, which is unscheduled at the moment.

Order-9 Bimagic Square

Bimagic means that you can sum the numbers as they are, or you can square them all first and then sum them. Either way, the square is magic.

David M. Collison, first discovered bimagic squares of order nine. An example is shown in Figure 1. He died before he could reveal just how he made it and mathematicians are still searching to find his method of construction.

Figure 1. Collison’s regular,   Figure 2. Hendricks’ newly
or associated bimagic square.   created bimagic variety.

In Figure 2, the square is partitioned into nine zones. These are not magic sub-squares, just zones.
Each zone of nine elements sums 369, as does’ each row, each column and both diagonals.
If you square all the numbers and then add them up, you will find that each zone sums 20,049,
as does each’ row, column and both diagonals.

With the new bimagic square, you can translocate any 3 by 9 rectangle of numbers to the opposite side of the square, as shown at left, and a new bimagic square will emerge.

About John Hendricks

Mr. Hendricks worked for the Canadian Meteorological Service for 33 years, and retired in 1984. Early in his career, he was a meteorological instructor for the N.A.T.O. Training Program. Later, he was a weather forecaster at various locations across Canada. Throughout his career, he was also known for his contributions to statistics and climatological statistics.

While employed, he also participated in volunteer service groups, including The Monarchist League of Canada and he was the founding President, Manitoba Provincial Council, The Duke of Edinburgh's Award in Canada. He was a recipient of the Canada 125 medal for his volunteer work.

Following his career in meteorology, he gave many public lectures on magic squares and cubes in schools and at in-service teacher's conventions both in Canada and in the northern United States. He developed a course on magic squares and cubes for the mathematically inclined students at Acadia Junior High School in Winnipeg for seven years. The resulting text book of over 550 8.5" x 11" pages was never published. He delivered half a dozen colloquia to professors of mathematics on the subject and in geometry and statistics, as well. He assisted in the Shad Valley program for several years.

John Hendricks started collecting magic squares and cubes when he was 13 years old. This became a hobby with him and sometimes even an obsession. He never really thought that he would ever expand the knowledge in this field. But soon, he became the first person in the world to successfully make four, five and six-dimensional models of magic hypercubes, and publish them. He has written prolifically on the subject in the Journal of Recreational Mathematics. He has also extended the knowledge of magic squares and cubes, especially the ornate and embedded varieties.

Update: January 30, 2004
Due to ill health and depleted stock, John's books are no longer available. He no longer has an e-mail address.

Sadly, John Hendricks passed away on July 7, 2007. I am still maintaining (Sept. 1, 2009) his original web site here.
