I t does. Thanks. However, if you want to rotate two opposite

corners, then you can use the "rube move" instead of 3,4,3. The

rube move was (partially?) developed by Rubik himself and is

thus:

r U r U r U2 r' U r' U r' U2

Hold the cube so that both are on top, one in the front, and one in

the back. r is also interchangeable with r', as long as each

instance is switched, of course. I like this move a lot. It was pretty

easy to learn, so therefore was the first I remember memorizing

from an outside source.

Oh, by the way, in #1- 4, which are the cubes that are

permutated/ orientated in relation to how one holds it? - Hi Grant,

Thanks for catching my goofs. :)

Concerning the two piece flip over. I thought I'd give a simple

sequence that he'd have to think about a little, rather than a more

complex all-purpose one like:

Do R' u R2 u2 R' Which flips over the UR edge piece first, and also

messes up the F2L a little, then turn U to any of the other edge

pieces on the LL, then undo the messing up by doing the sequence

backwards: R u2 R2 u R, then what ever U needed to realign the LL.

I'm not at all sure why I switched #s 3 and 4 because I do the edge

flipping before the placing

Regards,

David J

The sequences:

> permutated/ orientated in relation to how one holds it?

1. Move corners around: R U' L' U R' U' L

2. Rotate corners: R U R' U R U2 R'

3. Move edges around: F2 U r U2 r' U F2

4. Flip over two edges: r U r' U2 r U r'

Assuming we don't care about what happens to the other pieces, which

are affected by later steps...

#1 Swaps UFL and UBL

#2 Rotates UFR, UBR, and UBL clockwise

#3 Permutes UF -> UL -> UR -> UF

#4 Flips UB and UL and permutes UB -> UR -> UL -> UB

- Grant - Hey, thanks again, I'll be working on this for a while. I'm still

experimenting with what I want to use for now but in the

meantime, my sights on Fridrich. (I'll get there some day....)
