G perms!

[Schvetlana]

Does anyong have any tips on reconizing G perms and how to tell the difference quickly??? I am very bad at this! Thanks!

One tip is using the search function.

Type in "G perm" and you'll find...

Well I recognize my Pll's, especially the g perms by the pieces that are solved. Each perm has a solved corner and adjecent edge right? So look for those two same color edges that are opposite the pair. For example, The pair is in the bottom right spot, the two same color corners are on the back side. I instantly know that it's the perm that begins with L U L'. I don't know the sub letters for them yet though...Ga Gb Gc Gd, which ones are which?

Alright well for my recognition of the G perms, I look for two corners that match (color-wise) on one side. I put these two corners on my left side and look for a 1x1x2 block on the cube. Depending on the positioning of this block i do the required alg

What I did is learn 1 of the 4 G perms, then figure out how to do it backwards (inverse) and also mirror image (plus backwards for that). I suppose some people might actually have different algorithms, but it works for me. Notice how G perm looks different from the R perms and Y perm.

That's exactly what I do as well.

the way I do it, the 1x2 is key so I will U U U till I get it matching my f2l. if I dont have a 1x2, I look to see if corners are solved with U, U', U2. if yes, do the edge perm, cube is solved. (theres only 4 edge only perms) if not I will look at how many edges are positioned and how many are not. I have a branching system of PLL's. basically there are perms that move 2 edgies and 2 corners, 3 corners, 3 edgies, 3corners and 3 edgies, 4 corners, 4 edgies. six branches. you can make up your own system. I am learning g perms last cause I just 3 edge + 3corner algs back to back. but what I mean is the 2+2 is easy to see cause when you have 2 opposite edges solved you already know its a 2+2 perm. there is no other way. when you have two neighboring edgies you can usually just U U U till you get a three edge perm.
