Face 8: (BBB/BBB/BBB)/(BBB/BBB/BBB)/(BBB/BBB/BBB)
And a twist would jump all the characters representing stickers from certain faces to others in a certain way. If we represent the puzzle in this way, a twist is probably more difficult to follow than the graphically projected representation of MagicCube4D though.
I've seen textual representations that try to mimick mathematical projecting down dimensions too. These are more complicated in their organization but still contain the same total number of characters representing all the different colored stickers.
Hope this helped answer your question.
