Good memory.

It appears that most of your comments have been directed to Evan Liu. Since the three organizers played an equal role in organizing the competition, Kevin and I (Mitchell Stern) have decided to make the following posts. We would like to formally apologize for the organizational issues at our...

I would like a black one, if you haven't already received 24 pre-orders.

Werner, this topic is about swapping adjacent cross edges without disturbing the already-solved F2L pairs. For swapping adjacent cross edges right after making the cross, I'd suggest a slightly shorter alternative: z' U' R U R' U' z.

To swap DF and DL, I usually use M' y' M' U M y U2 M. It's 100% intuitive and fairly fast as well. To swap DF and DR, you could either do a rotation first then use the algorithm above, or use the mirror, M' y M' U' M y' U2 M.

To clarify: 1) Is the wall infinitely wide as well, or does it have a finite width? 2) Is the mass density of the wall uniform, or is it distributed in such a way that the wall has finite mass?

If you do a Sune on U, then a Sune on D, you have rotated 6 corners in the same direction.

There are no results to be displayed yet, as registration is still going on.

If you use the Roux method for a 3x3, why would you use reduction for big cubes? Methods like http://www.youtube.com/watch?v=llhAX09mjIk or K4 are surely more suitable...

I also ended up with a red/red edge...

Pop(s) perhaps?

This thread has been closed to avoid unnecessary conflict.

I have to disagree. After a little practice and getting used to, Fridrich F2L works well for the Mirror Blocks puzzle.

That picture is hilarious. :p Also, I agree with the Chinese translations given above.

British - practise American - practice I will, however, point out that Firefox doesn't think that practise is a word. :p

Agreed. This problem makes no sense whatsoever.

What is a "DeMoiyrean polar vector field"? The "Fundamental Theorem of Signs"? Google doesn't seem to know either.

Wow, that's quite a long algorithm. At 20 moves, it could easily be 1/3 of the total solution!

That would be quite a punishment.

How would you recommend improving the peg input? The number pad is only suitable for clocks of size <= 4.
