R' F R3 U' R2' U' R2 U R' F' R U R2'
I would do it with a regular R2 at the end, but either way that is a dumb alg lol.

Alright @Danny Gorlov take your pick -

Bar on left -

L U' R' U L' U2 R U' R' U2 R

x U2 r' U' r U2 l' U R' U' R2

F U' R' F R2 U' R' U' (R U R' F') (R U R' F')

Bar on back

L' U R' z R2 U R' U' R2 (U D)

Bar on right

L' U' L F L' U' L U L F' L2' U L

U perms / A perms for megaminx (probably not new):

R U R' U' L' U' L U2 R U' R' U' L' U L (A perm)
R U R' U2 R' U' R U' R U' R' U2 R' U R (2-gen variant)

R' U' R U L U L' U2' R' U R U L U' L' (U perm)
R' U' R U' R U R2' U R U' R U' R' (2-gen variant)

The 2-gen U perm is pretty nice, I think.

Since this topic is closed, I add here what I think can be a easy-to-remember help:

T-perm can be split in:
1. Sexy move;
2. sledgehammer;
3. sledgehammer;
4. a couple of rotations and a QTM;
5. sledgehammer;
6. (optional) another couple of rotations.

I added the algorithm to the wiki (now it is Alg.10).

The starting one is
R U R' U' R' F R F' R' F R F' U' F' U F U'
that becomes
(R U R' U') (R' F R F') (R' F R F') y' x' F' (R' F R F') x y

Best wishes,
Lorenzo

insertion finder spat out this weird edge 3-cycle that isnt a comm

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

you can shift the last move and solves the same case

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

So there's this adjacent parity alg for swapping UF and UR: [R U R' U' Uw2 Rw2 U2 : 2R2]

You can rearrange it a bit to get an alg to swap UB and UL: [Uw2 R U R' U' Rw2 U2 : 2R2]

Might be useful to avoid doing two U2 AUFs, but probably not that good on its own because you might need to regrip before doing the inverse sexy (or do it from an awkward angle).

alternatively Rw U Rw' R U' Rw' U' Rw U Rw U' Rw' U' Rw' R U Rw U R' U' R', very TPSable but long, it may be better than the standard though.

Triple post

rotationless N perm
R D' F2 R2 U' L F2 L' U R2 F2 D R'

this is just a setup to a ZBLL
i found a neat finger trick for this alg

l B’ D2 x R2’ U’ r U2 r’ U R2 x’ D2 B l'

you push the B moves with your left ring and double flick D2s with you right pinky/ring

Weird optimal L4C alg: x U R (U' D) L (U D') R' (U' D) r' B'

I normally just use r U R' U' M U R U' R' F R U R' U' F' for this ZBLL case. The weird alg is marginally faster, but I can't execute it reliably because the slice moves keep making my cube lock up.

Another weird optimal ZBLL alg from the same set: R U R' U' M' U R2 B' R' B U' r'.

I unearthed an obscure alg from algdb.net and added my personal touch.
I had to play it at least half a dozen times to convince me it does the job.

Indeed.
Maybe it is more interesting for the symetric Nb:
R' U' R U' R' L' U2 R U R' U2 L U' R U2' R' U R
…starting with right thumb on U.
