how many "non intuitive" 3cycles are there?

The ones I know are

[R B L F, U]
(L2 f2 L2 U)*2
R2 U R U R' U' R' U' R' U R'
R D2 L2 F U2 L2 D2 B R

Any others?
And it seems that there are only weird algs for edges

(M U M' U)*2

I don't really understand how this corner cycle works:
R U2 R' F2 R U2 R' U2 R' F2 R U2

[R U2 R' : [F2, R U2 R' U2 R']]

 

[Daniel Lin]

(L2 f2 L2 U)2 can also be solved with (f2 R2 U R2)2

mind=blown

L F R U' R' F' L' B' U B

cyclic shift of mirror of my first alg

the shortest corner cycle I could find was this Aperm: R2 D R2 D' F2 R2 U' R2 U F2

This is kinda related to the U perm, R U R U R U' R' U' R' U'

EDIT: regarding corner cycles... r U r' U' r' F r2 U' r' U' r U r' F' U lol

EDIT 2: I saved 2 moves R U R' F' r U R' U' r' F R2 U' R' also r U R' F' r U R' U' r' F R2 U' r' works too

yeah just a setup

EDIT: regarding corner cycles... r U r' U' r' F r2 U' r' U' r U r' F' U lol

wat

I'm learning these for FMC btw. Are there actually no other weird corners cases (that are 10 moves or less)?

 

[guysensei1]

wat

also r u r' u' r' f r2 u' r' u' r u r' f' u
is a pair 3-cycle

That's actually how I learnt the 2-gen U perm algs! I knew this one because I was using it for F2L, but it took me forever to realise I could conjugate it into a U perm.

An infinite amount if you don't limit movecount

Whoa US Nats is already almost halfway filled. Wonder how long it will take to reach 800.

Hey guys, Would anyone be interested in an AvG edge pairing tutorial? I want to make one cuz I learned it and I want to make it easier for others to learn. There are practically no tutorials online...

Is Kirjava still alive?

Is Kirjava still alive?

Yes. He posted on here a few weeks ago about another cool program he made (I think he occasionally goes to comps as well but I'm not so sure about that anymore).

 

[Shiv3r]

Hey guys, the AvG 5x5 edge pairing tutorial (written) is complete, It's here. If enough people like it, then I'll make a video tutorial.

I was browsing the farthest-back pages of the WCA front page, and I found that this:

doesn't match this:

Perhaps there was a third round that was later annulled?

They only had 16 competitors, so they weren't allowed to have a 3rd round, but I'd assume they weren't aware of the rule. Here is the link to the post on the WCA board about it

He's registered for Manchester Open this weekend.

On a 3x3, what's the shortest length of algorithm that flips any number** of edges in place and leaves everything else untouched? Is it 13 moves?

What about the shortest algorithm that flips any number** of corners but leaves everything else untouched? Is it 12 moves?

Also i found this cool easy to remember 12 move corner twisting alg
(R' U2 R F' D2 F)2

**non-zero number please

 

[xyzzy]

12-move edge flips: (M' U)4 and (R r y)6 and their rotations/mirrors/inverses/conjugates.
12-move corner twists: the one you posted + rotations/mirrors/conjugates. (Incidentally also an alg I used for the old FMC NR, lol.)

There's nothing shorter.

I just had a really weird 6x6 pop. I was doing a turn of the outer 2 layers during centers, and one of the outer wings randomly jumped across a center and forced itself into another edge. I had one edge group with 5 pieces, and one with 3. To fix it, I had to pop the extra wing out and put it back in its proper edge.

How does the cubing nemesis thing work?

Everyone who is a nemesis is faster than me at 3x3 but otherwise I don't get it much

A nemesis is someone who is faster than you in EVERY event.
