Yeah, if it was properly 4D it would be pretty unplayable I think, you’d need 4 each 4 layer cubes, and they could not be nested in any physical configuration.
You can show them as 4x4 boards of 4x4 squares.
Yes, but they can’t be meaningfully nested like the proposed one is. Thats the elegance of
The solituon provided, but it necessarily sacrifices symmetry to get there.
