Pantriagonal 20x20x20 magic cube (Composite 4)

 

Using a pantriagonal 4x4x4 magic cube and a pantriagonal 5x5x5 magic cube, there are three possibilities to construct a pantriagonal 20x20x20 magic cube.

 

Take as first grid 125x pantriagonal 4x4x4 magic cube and as second grid 64x pantriagonal 5x5x5 magic cube. See below the grids and result of level 1.

 

 

Take 1x number from first grid with 125x pantriagonal 4x4x4 magic cube [level 1]

N.B.: Extra magic feature is that each random chosen 4x5 or 5x4 rectangle in the levels and horizontal/vertical through the levels (= 4x5 and 5x4 compact in all three directions) give the magic sum.

 

See for all levels and check if all numbers are in the magic cube and addition of the numbers give the right magic sum, the download below.

 

With method composite 4 you use AxAxAx magic cube of order B and BxBxBx magic cube of order A or vice versa to construct a magic cube of order AxB. See on this website the construction of:

12x12x12 (simple)20x20x20 (pantriagonal)28x28x28 (pantriagonal),

30x30x30 (diagonal) and 30x30x30 (pantriagonal)
