[Cameron Almasi]

Hi,
IM constantly hearing stuff about commutators but i really dont have a good idea of what they are. Can someone plz describe to me what they are.
Thnx

Oh hey~!
I remember you from US open, i thought you knew how to use commutators?
We had a 6x6 race, and i assumed you knew by the way you did your centers.

I Like A B A' = conjugates

Ex:
A = R U2 R' F' L'
B = U / U' / U2 ... (pick one)

Makes an OLL

How does it work?

A setup all LL pices into LL
B makes a mix of the pices
A' restores

This thing = moving LL to LL using A can be done in many ways, shortest is A = R U R' F' One I like is A = R' U R2 D r', it makes a COLL if B = U2 else OLL, nice and fast =)

One more: A = R d' R2 D R

Edit:

this makes a nice picture of the function:

If we exchange

A = <-
A' = ->

Then the alg becomes <-B->

And that is wery intuitive, here my first example written like that

R U2 R' F' L' <-U2-> L F R U2 R' = it is mirrored from the middle and out.

Using arrows you can write the whole alg like this R U2 R' F' L' <-U2-> the rest is not needed. Maybe we should make it a standard?
