Well what I would do is imagine in my mind what the PLL would look like if that edge was flipped.Like what Syuhei does? Any tips on recognition? I tried it once, it took me ages to figure out whether it was just an edge flip or double parity :fpWow I think I might switch to: OLL, solve parities if there are any, PLL. (Instead of OLL parity if any, OLL, PLL parity if any, PLL.
Dang it Lucas! Thanks for the nice alg courtesy Grandmaster P, but you are seriously frustrating me when you make r' = (Rr)' = r' . How can you specify a single slice turn on a big cube with this notation method? I never know for sure with your algs to slice or not to slice. Stop it, or, or, or..... I might be revenge driven to post gobs and gobs of mystery algs using a combination of face color names, arrows, and compass headings!I'm not sure I agree with your title, but:
r' U R U (r' U2)3 r2 U R' U' r2 U' R' U r'
Yeh, its a good thing that I did, or that earlier post might have contained a few too many 4-letter algorithms. It's actually funny how I tried doing that a couple of times and was getting rather peaved, before I spotted the problem with the notation, and then also watched his applet to confirm my hunch. Lucas knows far too much to not know that (Rr) = r = (Rr) notation is confusing people wherever it is found.
Yeh, I WOULD use a computer to help me, but there aren't any programs (yet) that will solve this. Acube and CubeX find some 4x4x4 algs by limiting moves and setup, but not this one. These algorithm(s) are destined to become the new standards for flipping single edgepairs. Naming rights should go to the finder. Maybe even do a trademark funny like Petrus did with Sune™reThinking the Cube,
I actually was on the same page you were on. You and I do see eye to eye. And thanks for your appreciation! Well, if you really want me to try to find the "dirtiest" alg that does what you want, I will try. I will not use a computer in my attempts (I refuse to).
There is no need for a parity algorithm to be used before the last slot. It is pointless. There are a large amount of people with official sub-50 solves. As far as I know, they all use a form of reduction. They don't need a new parity algorithm to get fast. They get fast by practise. A new parity algorithm that messes up your last layer is not a 'new standard.' It is pointless.These algorithm(s) are destined to become the new standards for flipping single edgepairs.

That is, although I'm not convinced by cmowla's proof, I don't think there is likely to be a parity alg that is "faster, quicker, and cheaper than what we have now" - and even if there is, I really don't think it will be by very much.
I'm not saying you should completely stop looking, but don't think your idea is going to substantially change how 4x4 solves are done.
You are clearly not familiar with Dan Cohen's parity song.This new algorithm should also be simpler, and hopefully much easier to learn. Try teaching the 4x4x4 solve to someone not familiar with these parity algs, and then come back and tell me this won't make much of a difference. The existing parity algs are relatively hard for most to learn and master.
I really understand that. But I see no proof that this is the only way to do it.deadalnix, if you really understood how brief pure "edge flip" algorithms are formed, you wouldn't be soooo arrogant!
You can't prove I'm wrong so I'm right ? That's a very strange way to apply logic.It can't get any simpler than that. If you want more of a proof, deadalnix, find the shortest pure edge flip in the world (in block quarter turn moves) by hand, and then we will talk.
