How does an M-slice work?

[AgentKuo]

Like I get what it is, but how do you do it, and which direction is regular and which direction is prime?

 

[Julian]

M follows L.

 

[TheMachanga]

I'll ask this here.

Why doesn't it follow the R slice? I always thought that was most logical, because X follows the R.

What about E and the other one?

M: from top to bottom
E: from left to right
S: clockwise

 

[Rpotts]

E follows D, S follows F.

M = R L' x'
M' = R' L x

There is no concrete why, it's just arbitrary naming that stuck.

 

[SpeedSolve]

M: from top to bottom
E: from left to right
S: clockwise

He means what is E' and E, I assume?

 

[JasonK]

There's a lot of variation on how people do M moves - there's a whole thread about it here.

E and S slices are just the other two slices (afaik it's E for "Equator" and S for "Standing"). They don't tend to be used much in solves.

Standing?

 

[JasonK]

Standing?

I don't get it either, it's just what I saw somewhere. What else would it be, "Slice" maybe?

EDIT: From wiki notation page:
S - a move of the Standing layer (between F and B), in the same direction as an F turn.

 

[Rpotts]

Afaik it was
M - Meridian
E - Equator
S - who the **** cares?

How do you execute M quickly? M' is easy, in H perm, you can even double flick with the left hand's middle and ring finger. I'm having trouble finding a way to do M U quickly, it feels unnatural doing a M with left, so I do it with right, which slows down the U.

 

[Rpotts]

r' R

or you can push your right/left ring finger up from BD, but I only like that if it comes after an M'/M2, otherwise your hand's not really in the right position for it.

Here is an early reference using the EMS-notation: http://rubikscube.info/waterman/booklet.php

 

[Photon]

ok what? I realized I've been doing the 2LOLL's Z-Perm with M instead of M'. It doesn't make a difference... is this a one off case or does it really not matter?

 

[Ranzha]

It doesn't matter. M = y2 M'. Therefore, if you apply a y2 rotation: all the U-layer turns are the same as if the y2 never occurred; the M moves you were using become M' moves; the M2 moves remain the same.

 

[cubernya]

For those of you wondering what S would stand for, I always thought it stood for side. It makes sense

 

[Ickathu]

I thought it was:
M=L
E=D
S=B
because RUF are x,y,z, rotations...

 

[Kirjava]

It doesn't matter.

Yes it does.

 

[Ranzha]

Yes it does.

Not in that case. Otherwise, it can reeeally make a difference.

 

[Kirjava]

He said "is this a one off case or does it really not matter? "

You said it doesn't matter.

You should've said that it was a one off case.
