Ben is correct, in that the inner and outer cubes are included; in fact, the setup pieces are put there (on the nearer face of the "large" one, and the far face of the "small" one). That's a total of 24 faces.

And I'm even more confused than Ben about what you're suggesting with the numbered pairs.

I'll give a further example of how they're connected. A piece leaving Face 1 going "up" (as seen in the cubic illustration) has a choice of going to Face 2 (the top of the big cube) or Face 7 (the slanted face leaning down from the top of 1). If it's sliding orthogonally, then it can contiunue across Face 2 to either Face 6 (opposite Face 1) or Face 15 (which slants down from the top of Face 6), or across Face 7 to either Face 19 (the small-cube face "behind" Face 1) or Face 20 (the top of the small cube).

Then, as if that wasn't murky enough for folks limited to three dimensions: if the piece continues from there, it can then go to Faces 5 or 18 from 6, 20 or 24 from 15, 10 or 23 from 19, or 15 or 24 from 20 (that last being the first of probably several errors in the PDF document, which claims 17 or 24).

In order to help that, I suppose I could call the Home Faces White Zero (W0) and Black Zero (B0), and the ones adjacent to them White/Black 1-8 (or 1-4 a/b). The remaining six faces (currently the "Open Faces": 6, 11-14, and 19) could then be Grey 1-6.

I'd be afraid that that might be even more confusing, though.
