it is impossible to solve the cube using only the T-perm.

No, it's possible to solve all legal cube states with a t-perm and intuitive setup moves.

Well, I assumed T-Perm with setup moves was allowed.

Otherwise its pretty obvious that if no setup moves are allowed you can only cycle the same corners and edges back and forth. Hence the only solvable state would be a t-perm.

cube rotations also allowed, or am I wrong?

Your right, Haukzi needs to ltfm...

Today I experimented with doing random T-perms and cube rotations (no setup moves allowed), then trying to solve it using those same rules. A U-perm case cannot arise because T-perms can never lead to adjacent edge swaps. But the corners move and twist just about anywhere and I have trouble figuring out the solve. It's a nice little puzzle.

It's really fun, I have two corners misoriented ):

As of right now i LOVE the T-perm, using it to replace my CCW and CW corner swaps on 2-look PLL (cuz i'm so fast at it -- 3.39 xD).

i've got 2.88, 2.97 and 2.93,
just did 3 in a row as i had no idea how fast i could do it.

Rowe gets sub-1 usually...I think...
I suck at PLLs so I get around 1.5

I managed to do something like 1.30 on JunHyuk's new type a cube. With a bit of practise I could easily have improved that.

That's insane, I'd wanna find out who can do which perms fastest after that now =]

1.18
Now 1.09

It's impossible to get 13.37 on my stackmat, I've tried it 98432983 times...

The 1337 times are reserved only for the black versions of the mat. Mybe you will have better luck with 13:37.00

i thought it shuts off at 10 mins?

yeah it does.

on track, I rarely time my PLLs, but I did the T just now and averaged 1.95, best was 1.67

 

[mazei]

I think I did a 1.2x before. On actual solves maybe a 1.1x is possible. But doing around 7 tries on the spot now my best is 1.30
