It is the largest rubik mosaic ever built in Hungary (single or double sided). Created for the 2017 swimming world championships held in Budapest.
The planned size of the mosaic was 37*54=1998 cubes but the actual size had to be 36*53=1908 since they made the frame smaller than expected...
Idea:
Step 2a: (un)solve centers like U<->F R<->L.
Step 2b: solve centers + orient a few corners.
Step 3: orient remaining corners.
The point is at step 2b you can use very short algs like R' L R L', which solve centers and orient corners. Also, num of possible cases at step 3 got reduced...
That's a very good idea! I will think about how to do step 2 in en efficient way, to leave only low-movecount cases in step3.
Well, before doing a video i would like to make sure the method has potential. Yau's idea looks very interesting to me, i will experiment with it.
Yes i know of that case, but it is very easy to avoid. Thats the only case you should avoid.
Anyway, this method was planned as first 2 steps merged together, I just decompressed it to 2 steps for easier start for noobs.
I think i was wrong with that 729 algs. Its only 81 algs.
Basic idea is if you have 2 solved corners and all centers solved, then if you orient remaining 6 corners the only case you can end up is solved cube. So the num of cases for the last 6 corners are the possible orientation of them, which...
Don't wanna waste your time, so i give a short description of the method i came up with:
1st step: solve 2 corners + 2 centers between them. (intuitive, 3-4 moves on average)
2nd step: solve all centers. (very ez, intuitive, max 2 moves except 1 case which is 3)
3rd step: solve last 6 corners...
Please list all the competitions with the name of the organisers and the name of the side event, where there is a main event(2x2, 3x3, 4x4, 5x5, OH, BLD) having only 1 round, and a side event having at least 3 rounds.
Edit: list the main event too
- How did you reconstructed it? -
Watched it 4 times, wrote down your moves. Then cube explorered position, and inversed what it gave(thats why the short scramble).

Most of the good 2x2ers can do 1.53 avg of 5 and 1.80 avg of 12 if they are allowed >15s inspection.
Btw i like your videos, and it is amazing how fast you can turn the 2x2.
