# 5x5 Rubiks Cube edge algorithm

I'm following the tutorial on Ruwix, and either they're making a mistake or I am. When solving the edges they give the image:

This is my first attempt at a 5x5 and this step confused me for a long time, as it kept messing up my solved edges. I finally realised that the edge they have marked pink is NOT the one that gets broken, instead it's one further CCW. So instead of the algorithm u' R U R' u I find I need to do Uw' R U R' u (or have the broken edge further around on the TOP face).

Can anyone confirm this move, or hint at my mistake?

The move notation with small letters is ambiguous, as different sources use this to mean different things.

Ruwix's Advanced Notation page explains that they use the small letters to denote a turn of the two outer layers. This notation is often used on the 3x3x3 cube as well.

So yes, the site uses u to to mean what you know as Uw. For larger cubes they use $$U_2$$.

• Oh you are freaking kidding me!! I was following the 4x4 Ruwix page which says Lowercase letters mark inner slice turns. u' = Uw' U. Did not expect the same site to use two different notations :( – Ian Sep 9 at 22:30
• @Ian: Ouch! That's a pretty bad inconsistency. The 5x5x5 page itself should at least have a warning or explanation. – Jaap Scherphuis Sep 10 at 6:28
