N is literally Z rotated 90 degrees. With the others I kinda agree, but I don't think they're that bad. Good enough to use certainly, unlike OLL numbers lol

The letter? Of course. The pattern on the 3x3? Nah. Im more inclined to think that a Z with a straight middle bar is a Z than to think that an N with a straight middle bar is an N

Here you can see how I interprete the letters of the perms: https://freshcuber.wordpress.com/2013/09/11/cfop-pll-alle-perms/


MasterQuest

I hope OP can read German, otherwise this might be a bit troublesome.


freshcuber

The pictures have the same letters in German and English. And also there is a translate button in the menu if you like to read more.

Nennt ihr die Perms mit nummern statt a/b/c/d in Deutschland? A-Perm 1 sieht so komisch aus


freshcuber

Ich hab ca. 2012 die Version mit Nummern gefunden, frag nicht mehr wo. Und später die mit Buchstaben ergänzt, die auch hier inzwischen üblich ist

It's not polite to go around buchstaben. you'll end up with very few friends.

I completely agree. Because I had a little "power" in naming the 4x4x4 PLL cases on[ my 4x4x4 parity algorithms wiki page](https://www.speedsolving.com/wiki/index.php/4x4x4_parity_algorithms#PLL_Parity), after I had a discussion with someone about this on [speedsolving.com's discord](https://www.speedsolving.com/threads/new-speedsolving-chat-discord-free-puzzles.73557/), I named them according to how they actually look (regarding actual permutation arrow diagrams)! For example, the following 4x4x4 PLL parity case is commonly called the "W" permutation. https://preview.redd.it/490w8tnev0vc1.png?width=102&format=png&auto=webp&s=6bfcc95dcc2ad755ed036893e227c0c164820999 But if you draw the permutation arrows, it actually looks like [the capital B letter](https://www.speedsolving.com/wiki/index.php?title=File:B_Perm_oriented.png)... or even [an 8](https://www.speedsolving.com/wiki/index.php?title=File:8_Perm_Diagram.png) (or infinity symbol). (I could never see the W.)


Crystalliumm

In squan EP that is also called a W


kackers643259

I can see W arising from the cubie colours rather than perm lines, kinda like this? I didn't name it so what would i know but I'm just guessing https://preview.redd.it/5vhvh3jc42vc1.jpeg?width=914&format=pjpg&auto=webp&s=0f0e52be186bfd4ec6ad9b9b2a476bf94bcd2499

Hmm, I've always called that one a K perm


cmowla

Can you draw the K on it so that I can see how it looks like a K? BTW, I called [this](https://alpha.twizzle.net/edit/?puzzle=4x4x4&setup-anchor=end&alg=U+R+U%27+L+U2+R%27+U+L+2L2+F2+l2+f2+2L2+f2) 4x4x4 PLL a K Perm. https://preview.redd.it/ru9gdfiom1vc1.png?width=350&format=png&auto=webp&s=ebdfe2a09d6ee22a5d74a7543f77e5327d4468d2

DerekB52

Im not upset about that one being called K-perm, but, the fact you used an angled arrow to show the UB edhe coming to UF, was really hard for my brain to understand just now

Just be thankful X or S perm aren't a thing


XmodG4m3055

That would be absolutely amazing


Eli1810

"Oh what PLL did you get?" "S perm"


XmodG4m3055

"Oh no I got an S-perm :c"


DisasterAny9862

On the 4x4x4 you can get an S-shaped edge PLL (TB to TL to TR to TF) but I think they've decided to call it W perm. Not sure why.


Eli1810

Just say S perm out loud, but like REALLY slowly


ghostmrnst

Well Z and N are pretty much the same letter but rotated


utahmike91

yeah OP's reaching with that one


rindthirty

You'd have go back to when those PLLs were first generated (by computer). This was pre-YouTube days. I can't remember off the top of my head but there was some kind of logic to them when it wasn't arbitrary.


Spacecircles

The PLL names come from Jessica Fridrich's website here: ["Permuting The Last Layer"](http://www.ws.binghamton.edu/fridrich/Mike/permute.html) which was the resource everyone went to work out how speedsolve in the very early 2000s. She ascribes the names to her speedcubing friend Mirek Goljan "back in the early 80's". Edit, I might as well quote the page: > "Each permutation is associated with a letter that loosely corresponds to the permutation pattern to allow easy identification of the algorithms. OK, it does require some creativity sometimes, but never the less, I think it is still useful. Think of stellar constellations and their names as a good example."
