    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'

    I should probably learn to recog those weirdo edge comms for fmc...

    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.

    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

    A PLL V I've just built: (R U2 R u2) (R U' R' D' R U R2' F2 R D' L2)

    I wonder if it's new.

    I've personally never seen it before. But i really like it, it really seems to fit my turning style.

    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'.

    Wow, that PLL G!
    (U) F2 r2 (R2' D R2 D') (R2' U R2 U') r2' F2

    Where did you find this? I can't believe such an awesome alg for that case does exist. :D

    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.

    Seems to be similar to the standard alg, [R U R' U: Jb perm], but with a different Jb alg.

    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.

    R U R' F' R U R' U' R' F R U' R' F R2 U' R' U' R U R' F'

    I feel like this alg (J cancelled into T) is a better EP alg for megaminx than L R U2 L' U R' L U' R U2 L' U2 R'

    Or maybe its just that my lefty moves suck
