This has probably been discovered already. If so, sorry. If not, try doing a Ua/Ub-perm replacing the R moves with Rw. So R -> Rw, R' -> Rw', R2 -> Rw2.

Keep repeating. Every 4 repetitions it does something significant (flips edges and cycles DF -> DR -> UR.)

Not particularly useful, but I thought it was cool. I guess it would be nice to know how it works, I'll have a look when I have some time.

every "wide U-perm" cycles the centers by one M move, messes up some edges and leaves the corners where they have been. so it is not that surprising that after 4 repetitions the centers are correct again and just some edges have moved...

4x4x4 <R,r,U> stuff found by hand:

an OLL
Rw U2 Rw' U' R U r U2 Rw'

a rather long PLL parity
R U2 Rw' U' R U r U2 r' U' R' U r U2 r U R U' r' U2 r U R' U' r' U2 R U2 R'

a pure 2-flip
r U2 r' U' R U r U2 r' R2 U2 R2 U R' U' R' U2 R

another PLL parity
Rw U R' U' r' U2 r' U' R U r U2 r' R2 U2 R2 U R' U' R' U2 R r2 U R U' Rw'

and another PLL parity, this one isn't that bad
U r2 U r2 U2 r2 U2 r2 U r2 U2 r' U2 r2 U2 r2 U2 r U

okay this is just silly
r2 (r U2 r U2 r U2 r U2 r)2 r2
= r' U2 r U2 r U2 r U2 r2 U2 r U2 r U2 r U2 r'

it also works with Rw's
U Rw' U2 Rw U2 Rw U2 Rw U2 Rw2 U2 Rw U2 Rw U2 Rw U2 Rw' U

and an OLL parity. lol
Rw U2 Rw U2 Rw' U2 R' U2 r U2 r U2 r U2 r Rw U2 Rw U2 Rw' U2 Rw' U' Rw2 U R2 U' r U R2 U' r' Rw2 U

I remember phil Yu telling me that Stachu and himself worked on algos to solve a twisted corner that's been put in its right spot and also finish the oll (with all edges oriented) simultaneously. He showed one of those cases in his oh walk through solves. I'm pretty sure its not cls cos he said there are around 40 cases and he's yet to come up with a good name for it. anyone with an idea of what it could be?

That's just EJLS. It's a subset of CLS.

Has anyone tried playing the wikipedia game - but on the WCA official results pages?

As in....start at one cuber and try to click the least links while getting to another goal cuber.

I normally go from my page to some arbitrary world-class cuber, but I'm sure if we could randomize the start and goal pages, this could be fun!

I was thinking of using Petrus for the first 2 layers and after that getting a cross on the last layer and then i could use a CFOP style last layer with one of the seven OLL's for the cross and then have the PLLs. Do you guys recon this can become at least sub 15 with practice?
Or should i just learn Full OLL ?( i already know full PLL)
