How to use a panmagic 4x4 square to produce a perfect magic 8x8x8 cube?
The first known perfect magic cube of order 5

Walter Trump and Christian Boyer, 2003-11-13

The above mentioned 5x5x5 magic cube has the following magic features:
- the 5 rows, the 5 columns and the 2 diagonals in each level give the magic sum of 315:
- the 25 pillars give the magic sum of 315;
- the 30 diagonals (for example 115+64+38+87+11=315 or 106+44+58+87+20=315) through the 5 levels give
the magic sum of 315;
- The four space diagonals (for example 67+39+63+87+59=315) give the magic sum of 315.
You can use a 4x4 panmagic square to produce a perfect magic 8x8x8 cube in the next four steps:
■ Use the pattern of a 4x4 panmagic square to produce the basic pattern of the 1st level of the 8x8x8 magic cube:

■ Produce the basic patterns of the remaining levels of the 8x8x8 magic cube by swapping the 4x4 sub-squares of the
1st respectively 3rd level:
- Produce the basic patterns of the 2nd, 7th and 8th level by swapping the 4x4 sub-squares in the basic pattern
of the 1stlevel (see below colours yellow, red, pink and blue);
- Produce the basic patterns of the 4th, 5th and 6th level by swapping the 4x4 sub-squares in the basic pattern
of the 3rdlevel (see below colours grey, white, green and brown).
■ Add in each level two fixed Sudoku patterns to the basic patterns and produce the level by adding 1x digit from the
basic pattern to 16x the digit from the same cell of Sudoku pattern [1] and by adding 64x digit from the same cell of
Sudoku pattern [2]:
Basic pattern, 1st level Sudoku pattern [1], 1st level Sudoku pattern [2], 1st level
