Roice, that was a great article! Some of those numbers make
the number I found look like nothing! Thank you again for
putting my result on your website.

spel_werdz_rite, thank you for verifying this result! I had
no idea anyone else had calculated this number.

I recently had another idea for Magic120Cell before I go
back to the n^4 cube. It seems like it will be very difficult,
but I am going to try to find the number of visually different
positions of each of the other variations of puzzles (the
2-colored, both 9-colored, and the 12-colored versions) of
Magic120Cell. This will involve accounting for the similarly
colored pieces (4-colored pieces with the same colors may not be
visually identical due to their orientation, and counting the pieces
will require the use of the Magic120Cell program), and the similarly
colored centers (accounting for apparently different positions
acctually being visually identical due to rotations of the entire
puzzle in 4-space; the corner orientation logic would also apply
to the centers for counting how many ways the they can be visually
identical when rotated. This would be made eaiser by imagining the
0-colored piece that Roice mentioned.) These are just a few quick
observations, there may be more complications I am not yet aware of.

All the best,
