Nice work Andrey! 4032 pieces and 12288 stickers is what my formulae in Excel tell me, which is more pieces and stickers than the 3^7, even if it has one less dimension (which at this scale doesn’t even matter as much). I wonder how long it will be before someone conquers the 4^7 or even the 5^7, and I wish good luck to anyone attempting them, as it will require a lot of patience! What are your plans now Andrey? Any more huge puzzles to solve, or are you working on the speedsolving now? Speaking of which, it is amazing that you were working on this at the same time as getting some really good times on the 3^4! I can only wonder how you managed it all. Congrats again :)

I had serious orientation problem in the end of 5C stage (3-cycle of one last piece; it looked for me like 5C orientation of 3^5, that is very difficult for my algorithm), but now I see that there was easy way around this problem). Timer shows 40+ hours, but it started at the middle of 3C, so actual time is close to 70h. 175K twists, with longest macro of 65 twists (swap of 5C).
