Thank you for adding the new puzzle so quickly. I’ve added five new entries in the wiki page:

under 4D: 8-cell for the five new mirror cubes. I added your solutions to Mirror_A and Mirror_D. Feel free to make the records more accurate.

Melinda, I think Mirror_Z is not trivial at all. The 3D counterpart is the Rubik’s Cube with 180-degree turns only (half-turn cube), because the 2D inversion is a 180-degree rotation. It’s much simpler than the original Rubik’s Cube, but nobody would say it’s trivial.
