Twisting individual corners in alg.cubing.net

[gerzytet]

In alg.cubing.net, you can twist corners!
Here's the algorithm I used:
L' R' 4D R 4D' L 4B2 L' 4D R' 4D' L R D 4L F 4L' F' D' 4B2 D F 4L F' 4L' D'

This is possible because when you enter a move like "4D", it turns only the stickers of the U face, and not the pieces.
I'm interested in knowing what the shortest algorithm to do this is, as mine is pretty long. Edge flips and other rule-breaking weirdness should also be possible with this bug.

New Nb Perm: R L 4D2 R' L' U' R L 4D2 R' L'

Congrats, very clever!
Seems it also generalizes to large puzzles: https://alg.cubing.net/?alg=L-_R-_5...F_5L-_F-_D-_5B2_D_F_5L_F-_5L-_D-&puzzle=4x4x4

Definitely curious what the shortest corner twist would be!

(In any case, alg.cubing.net development is effectively frozen and I'll probably leave this bug in place. But if you ever see an issue like this in Twizzle, please let me know immediately!)

Solving a 3x3 like the centers of a 5x5:
F 4L' B U 4L 4F' U' R' z2 4R F 4D' F' 4L2 D' 4D' F' 4D 4R2 F 4R2 E 4D2 F 4D2 F' 4B D 4B D 4L 4B' U' 4B2 D 4F D 4F D 4L U 4L' 4F U' 4R D 4R D' 4L' D2 4R D2 4F U 4F2 U' 4R' U2 4L' 4R' U2 4R (U2 F2)2 4R' (F2 U2)2

Essentially a commutator from UFR to RUB to FUR, and then 4L at the end to actually make it look like a corner twist. This only works because the cube is solved though. If you want a corner twist on any scramble, you have to do 4L' first to actually make it a commutator between the stickers of the corner you want to twist.

This is what non cubers expect me to do whenever they twist a corner

Also to flip an edge:

So this is zeroing

this is not a bug, it's a feature!

let's get crazy and invent new methods and algs for this stuff

Just slightly modifying @Jorian Meeuse 's second single edge flip alg for the 3x3x3, 10 move OLL parity algorithm. (If only it was that simple, LOL.)
R 6D 2L' 2R 6D' R' 6D 2L 2R' 6D2

A real 9-10 move OLL parity algorithm will scramble the 3x3x3 pseudo state + destroy 3 centers!
r' U R' U r U F2 U r'

@Filipe Teixeira , thanks for bumping this thread! I haven't seen a gem on these forums in a while! (This feature can be used for puzzle theory-related topics for sure... even for "legitimate" topics, not just "imaginary" puzzles.)
