corener permutation and edges orientation/allowed moves

[deadalnix]

We that we cannot permute coreners using only RU. We need to add another face like D, L or F usualy.

Diagonal permutation need 4 extra face turns, and and to adjecent corener needs 2. If you don't change edges orientation.

If you change edges orientation, you can permut corners diagonaly using only 2 extra moves (FRUR'U'F' for exemple).

These knowleges are quite practical for me, but I'm looking for a deeper understanding of the mecanisms involved. If you have any idea, please share

F (R U R' U')*3 F'

Ok, there is one thing wrong in my forst post

But i was expecting more explainations

 

[trying-to-speedcube...]

There's nothing strange anymore now, is there? So why do you want more explanations?

 

[deadalnix]

WGy can't you (neither me) permute two corners using RU moives ?

That's seems trivial for you ?

 

[trying-to-speedcube...]

In your first post you said that it was clear to you.

Your question was: Why do you need to do 4 other turns to permute 2 corners diagonally?

I gave proof you don't have to...

His site is in the process of being moved to a domain and new server, and he is also working on some major updates.

I'm sorry if I sounded rude or anything... The last thing I want on this forum is a fight

But on-topic... I really don't know... :O

All edge PLL's can be done with only RU
For corner PLL's you need 1 extra face-move like L+L' or F+F'
For orienting edges you need FUR (might be disguised as MU)

If you learn a orient-first, permute layer method (for blindfolded for example) it should become obvious why this is true
