Classic Compound of 3 Cubes Plus 1
I have no idea what the name of this model is. I got the idea to add to 4th cube myself, though this is quite a trivial step. This result is pretty surprising. It has some peculiar properties:
- You can make a model with 4 cubes, and use 3 colours in a regular way.
- Adding the fourth cube results in a model with less separate faces (24 less)
- The resulting model is easier to build and more stable than the classical compound of three cubes.
