So-called "magic" squares and dito cubes bear that name wrongly in my opinion. Therefore the name "harmonic cube". At this model I have been looking for optimal harmony. In the three dimensions and to the four body diagonals for each row of four little blocks applies: Σ=130. Moreover that holds in bundles of 2 x 2 little blocks too. Jaap Geluk.
