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...

I don't see how the step-3 algorithms are 81. Edit: i see it now :D

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.

Here are all the cases for step3 which can be solved in at most 7 moves. Try to form the substeps using these algs.

Wrote skewb solver. Gave it my ideas, and waited for results (movecounts, num of cases).

I can't, I don't have a skewb :D

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

Do you have access to the scrambles? Is there a database containing them?

If anybody found my Piti Pichedpan bag full of cubes please pm me. Thx.

2.18 and 1.75 should be +2. With both counting, avg is not even sub-2 (2.24).

- 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).

What about average number of podiums? (number of podiums / number of competitions) Interested in top-100.

Thats a great idea. Please calculate sub-9 and sub-8 as well.

Thanks. Btw it was OLL skip.

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.
