|Notes on Magic Squares and Cubes|
|by Walter Trump|
There are more magic squares of order 10 than elementary particles in our universe and in trillions of other universes (if they exist).|
Number of magic squares
The results of historical and computer enumeration of magic squares
Trimagic 12x12-squares are known since 2002-06-08.|
Trimagic Squares of order 12
Here some new squares with special properties will be presented.
For example: a trimagic square for the 60th anniversary of LEGO.
Graphic interpretation of magic squares|
Area Magic Squares
Each area size is equal to the associated entry of the magic square.
Area magic squares were first suggested by William Walkington in December 2016.
Bimagic squares are still magic when all entries are squared.|
All bimagic squares of order 8
There are exactly 192·136,244 = 26,158,848 bimagic 8x8-squares.
We found them all! Co-author: Francis Gaspalou
Ultramagic squares are both pandiagonal and centrally symmetrical.|
Ultramagic squares of order 7
Properties, transformations and beautiful examples of these squares.
Read how to determine all 20,190,684 different squares.
2 + 8 + 9 + 15 is a magic (trimagic) series of order 4.|
Magic series (NEW 2019-11-12)
Yukimasa Sugizaki calculated the number of many further series up to m=4000.
Katsuhiro Endo independently calculated the number of series for m=4000.

Estimates of the number of magic squares (cubes, hypercubes)
Magic series and probability considerations enable us to estimate the numbers of magic objects.
