why tho
M moves can make algs so much better
but then 99% of the algs I'm getting have E or S

I don't think writing a program which can do that, and especially generate the algs quickly, is particularly easy...

I don't think an alg that works well with E or S moves would have a great solution with M moves unless you rotated

I think he means that an algs that has moves from the subset {R,U,L,D,F...} can often be made better if your use M moves as well as the standard outer turn moves.

Ellis Landers now has OH ao5 and ao12 UWR's. I'm really curious as to who he actually is. I would imagine at that speed he's been to a comp before, but he must be registered under a different name because both 'Ellis' and 'Landers' searches don't turn up anyone likely to be him. Although it would be really funny if that's actually Keaton.

Countries in South America ordered by those with most cubers who have competed first?
(aka what countries in South America have the most cubers?)

Can someone confirm if God's number for this Qiyi puzzle is 7?

and is there a way to do this in ksolve?

Looks simple enough to brute force. It's a bandaged Rex cube isn't it?

Also a pyraminx without tips or edge orientation, or a skewb with four corners removed.

Move count distribution:
0: 1
1: 8
2: 48
3: 288
4: 1640
5: 7582
6: 15262
7: 4221
8: 110

Can you give an example of an 8 move position? I wonder if they're interesting looking or just messy

3-cycle three centres around a corner and 3-cycle the other three centres. (Doesn't matter if you do the 3-cycles both clockwise, both anticlockwise, or in opposite directions; all of these are 8-movers.) I haven't checked the other eight-movers, but most of them are probably messy.

wow, I tested one of them and it gave almost 100 different optimal solutions

feliks friday four episode #23

4th or 5th fastest solve of all time I believe...

1st bill wang PB 3.70
1st Feliks PB 3.7x
3rd Dmitry Dorbachev 3.93
4th this I think...

I could've missed one...
(drew said his 3.72 didn't count...)

 

[1973486]

"Dorbachev"

Bill has a high 3 and Feliks has at least 3 3s.

 

[gateway cuber]

like I said, I could've missed one...
I thought Bill's signature said his PB was 4.15?
Anyway still a realllyyyy fast solve.

 

[1973486]

IDK, he posted a 3 in the Accomplishment Thread recently though.

 

[gateway cuber]

oh yeah that's right, I'll put his solve in my post...

 

[Cale S]

Doesn't Rowan Kinneavy have a 3?

 

[gateway cuber]

who's that?

 

[1973486]

https://www.worldcubeassociation.org/results/p.php?i=2008KINN01 I'd be surprised if he does though...

It might have been like a low 4 or possibly high 4, I remember seeing a reconstruction with a super lol F2L and LL skip or something
