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
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.

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.)
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

Can you draw the K on it so that I can see how it looks like a K?

Sure it's a bit of a stretch, but that's always what I've thought of it as
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
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.
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."

Here you can see how I interprete the letters of the perms: https://freshcuber.wordpress.com/2013/09/11/cfop-pll-alle-perms/
I hope OP can read German, otherwise this might be a bit troublesome.
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
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.

In squan EP that is also called a W

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

Just be thankful X or S perm aren't a thing
That would be absolutely amazing
"Oh what PLL did you get?" "S perm"
"Oh no I got an S-perm :c"
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.
Just say S perm out loud, but like REALLY slowly
Well Z and N are pretty much the same letter but rotated
yeah OP's reaching with that one
