Way to distinguish L shape OLL47, 48, 49, 50, 53, and 54

There are 6 OLL’s of L shape (47, 48, 49, 50, 53, and 54). It is necessary to find out which it is.

At first, I divided them into 3 pairs, based on its mirror relationship. So, 47 and 48, 49 and 50, 53 and 54 are mirrors respectively.

I put the first one of the pairs (47, 49 and 53) at upper left portion of U-face, and the second one at upper right portion.

And I adopted the mirror method using by my right and left hands.

But with this method, I needed to position them correctly after looking for “key” (bar, headlight, etc.) and understanding if it is a original or mirror.

So, I changed my method. I position all of them at the upper left portion, and distinguish them looking at F&R faces as follows.

F-face / R-face -> OLL No.

colored edge / block -> OLL47

block / colored edge -> OLL48

bar / block -> OLL49

block / bar -> OLL50

colored edge / bar -> OLL53

bar / colored edge -> OLL54

I don’t use algorithms for their opposite position (lower right portion of U-face), to avoid confusion. So, I will show only one algorithm I use for each OLL.
