4x4x4 edge swap

[kinetic]

Last summer I had found a cool alg to switch just two edge directly across from each other. I can't find or remember the alg. Does anybody know it?

2Uu 2Ll 2U 2l 2U 2Ll 2Uu

How do I position the cube?

One edge at the front-Up position the other in the back-Up position. This is in any beginners 4x4 video in the last part of solving it as a 3x3.

Even shorter is 2r 2U 2r 2Uu 2r 2u ...

That's the algorthm I use! It's a great alg. Same positioning as hic0057's alg, but FASTER! Use it, kinetic!

Seriously what's with the messed up notation?

In official WCA notation:

Uw2 Rw2 U2 Rw2 R2 U2 Rw2 Uw2

Yes that does work. But it switche edge pairs. I want to switch just one edge.

l' U2 l' U2 F2 l' F2 r U2 r' U2 l2

l and r are inner slices only.

Yes that is the one I was looking for. Thank you.
