Hi Hugh. I haven't been on here of late. Just too busy.
I would suggest that this VRI is an example of a rotated & mirrored (+/-) set of four 3D spaces with each identical to each other except for different mirroring/rotation combinations.
I think that saying four spaces - for VRI - is a little more accurate than saying 'multiple'; and as long as they remain identical to each other while differently oriented.
This was one of the differences that I had been meaning to offer to you to explain the difference between your VRI 4D and the spatial 4D understood here.
The spatial 4D, generally discussed at this site, has a full 360° of rotation; not just 4 aspects of that rotation.
If you were limited to only flipping 90° at a time, in the spatial 4D here, then you would get a similar effect to your VRI.
In a true 4D space you would not be limited to this 90° flipping.
Having thought of this, but not having had a chance to express it to you yet, I hope this helps you to understand the difference better...
Cheers.
