When solving a 4x4 cube you have specific notation to inner and outer lines, like R
= Clockwise outer right and r
= Clockwise inner right. If you want to turn both, the two letter must be combined like Rr
, (Rr)'
or (Rr)2
. To solve OLL parity I could use the following algorithm:

r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2
If r2
means "turn inner right 2 times clockwise", why some sites uses r
as Rr
?
Example:
- Open Alg Cubing
- Select 4x4 cube
- Inside the Moves field, type
r
- Play. It will turn both right columns.

- This site uses the notation
r
to define "both layers(outer and inner)". - However, this site uses the notation
Rr
to define "both layers"
My question: What is the official notation to 4x4 movements(if any exists)?
r
and the outer-right slice asR
. This appears to be consistent with the other two sites. $\endgroup$r
means both layers and2R
means inner layer $\endgroup$
