Nan, thank you!
I don’t know about next challenge. It should be some coding - to implement more puzzles in MPUlt, to write a couple of non-puzzle games in 5D, try to do something with {5,3,4} (I feel that there should be periodic patterns - like 22 colors for {5,3,4} and 55 for {4,3,5})… But may be I have a new challenge for you - try 600-cell in new version of MPUlt (uploaded today) ;)

Good luck!

For each type I select some cell, change it to white, then move all cubies with white stickers to this cell (using setup unwinding and a couple of macros). My goal here is to make all stickers of the current type on that face "white". Then I use another macro to sort cubies in that cell (it is a half on 3-cycle that moves two pieces from the cell and one outside). Non-macro twists here are twists of one cell, so I don’t need to use F1/F2/F3 keys for this stage. Then I go to other cell and so on.

I think that I lost about 6 hours of displayed time here. But at the end of 3C stage I found that situation is much better than I thought about it: timer displayed 57h 05m! So if I’ll be solving 40 pieces per hour, there will be good chances to finish at 72h :)
