2x2 Ortega method similarities to 3x3

[Zarxrax]

I'm just starting to learn the ortega method for the 2x2, using erik's page here: http://erikku.er.funpic.org/rubik/2x2_ortega.html

I spent a few minutes trying to memorize the first algorithm before it hit me--I already know that algorithm from the 3x3!

So I was basically wondering, which of the ortega algorithms are the same as normal 3x3 OLLs and PLLs? Perhaps all of them? Knowing which ones are similar would help me greatly with memorization.

First row - All oll's

Second row - The first 2 are pll's

No, not all the OLLs. R2 U2 R U2 R2 is not a 3x3 algorithm but it's VERY useful for 2x2, doing the case basically any other way is very slow...

You can use OLLs for those algs, but they will be longer, because they have to keep edge orientation.

Not necessarily. One example is using F R U R' U' F rather than U' R2 D R' U2 R D' R' U2 R'; the first does not preserve edge orientation, but is much shorter, and they do the same function in 2x2 Ortega.

First of all sorry for waking up this old thread. But I have an Ortega 2 X 2 question.

I have my B face all red solved (OLL only) and have a green bar facing me, on U face I have all orange but no bars or anything. What can I do? I normally solve this by doing just R2 U R2 y' U2 R2 U R2. This leaves me with a solved B or U face (PLL wise) and I can do the Face that is left with R U2 R' U' R U2 L' U R' U' L. Is there a faster way?

Never mind, I just found the answer on Eriks page. L D' L F2 L' D L'
