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']]

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

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.

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

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.
