can you translate these two algs for me?
I don't understand commutators notation at all...

1) [U' : R' F' R, S] M2

2) M2 [U' : S, R' F' R]
1) U' R' F' R S R' F R S' U M2
2) M2 U' S R' F' R S' R' F R U

So,
[A, B]= A B A' B'
For example: [R, U]= R U R' U'
[R U R', D']= R U R' D' R U' R' D
[A : B, C]= A (B C B' C') A'
For example: [F : R U2 R', D']= F (R U2 R' D' R U2 R' D) F'

Commutators follow the format (A B A’ B’). Either [Insertion, Interchange, Reverse Insertion, Revere Interchange], or the other way around.
Sometimes, you might have a setup move before the alg. That means to do those moves before and after the full comm.
So, [U' : R' F' R, S] is (U’ R’ F’ R S R’ F R S’ U’)

Difference between GTS1 and GTS?

Nothing, people just sometimes call it the GTS1 to differentiate it from other gts line releases

The last move he asked about is U, not U'. That being said, I don't know what it is called.
oops, I thought I saw an apostrophe =P

odds of 1/10 and 0/10 (parities) ao5 for 4x4? Just got a 1/10

#### Sue Doenim

I'm pretty sure 0/10 would be 0.0000953674316%, but I'm not totally sure about 1/10. My guess would be 0.001907348%, but I'm not sure if that's right.

Do the Valk and Valk Power have the same screws, springs, or center pieces?

How would you say r (or any other lower case letter).

#### PowerfulCity

We usually just say it with a wide at the start. For example, r would be said as “Wide R”. b would be said as “Wide B”

What about for puzzles that could have multiple types of r wide (bigger than 3x3?)

#### fun at the joy

I'd say small "R"

#### brododragon

for r, and Rw(big cubes) I'd say R slice and wide R
I mean like, say, on a 5x5, how would you say a wide r that turned 3 layers vs 2 layers
