For those who didn't know already, Eli Jay's 1.8 UKNR skewb single was 11 moves, making the solve almost 6TPS.

Odder could have named his 5x5 Hoya variant Oscar De La Hoya.

How many ways are there to resticker a Rubik's cube given a 6 colors, 9 identical stickers per color? 1 sticker per square obviously. As a useless bound, it's somewhere between 43 quintillion*12 and 54!
And how 'groups' are there in those? A 'group' is a bunch of stickerings which can be turned into one another by turning the Rubik's cube.

The first question is easy. It's 54! = (2.31x10^71) if there are no restrictions on combinations of stickers.
The second question is a lot more interesting. FYI, these are called orbits. My first guess as a rough estimate would be 54! / 43 quintillion. This won't be correct but I imagine it's close.

Are you sure? 54! would be correct if all stickers were distinct but for a cube they're not. (6 groups of 9 stickers)

Oops. That somehow slipped my mind. You have to divide by the number of ways each group of 9 stickers can be arranged. This means the answer is 54!/((9!)^6) = 1.01x10^38. The relevant formula is permutations of multisets.

Ah, I actually know this formula. Didn't think of using it. I think this number should be further divided by 24 to account for double counting different orientations of the same state...?

There are states that don't change after being rotated

yup, so its a slightly bigger number than what youd get just dividing by 24
so how would you calculate it then? Would you have to do a case by case analysis to see which states are symmetrical?

So apparently the upcoming Cong's Design pyra and skewb will have magnets instead of ball bearings. Seems pretty interesting, but it'd be impossible to change the clickiness without getting new magnets. Thoughts on this?

I got a 1.98 on 10 move solution so 5tps

It looks like there's a problem with this competition's cubecomps. Everyone who had a special character in their name got cut off, leading to competitors named "Mois" and "Jes" with no last names.

Why is it that the scrambles listed here for FMC do not start and end with R' U' F even though the comp was after the scrambler change?

Maybe everything was printed out and genned before the regs took effect?

Probably an outdated version of tnoodle.
Official competitions must always use the current version of the official scramble program.

So just out of interest, has anyone actually tried 4x4x4 FMC seriously? I feel like it would be an interesting puzzle because you would need to balance a lot more things than with 3x3x3.

I think most attemps consist of cage method and then inserting center comms afterwards
