4x4 edge pairing parity alg

Nice alg. I'm going to have to switch since mine is sooo long

u' R U R' u U2 R B' R' B u' R U R' u

Basically said, false pair, set, flip edge, connect pairs
 
I use the Uw' R F' U R' F Uw one too, indeed.
As far as I know, it is the shortest one.

If you don't like learning lots of different algorithms and you are planning to buy bigger cubes later (or if you already have cubes bigger than 4x4), you could kill four birds with one stone and learn the algorithm that sends the outer edge to the other side and vice versa (l' U2 l' U2 F2 l' F2 r U2 r' U2 l2), which you can then also use for the 5x5, 6x6, 7x7, but I still prefer Uw' R F' U R' F Uw though. There is no real point in using such a long algorithm on a 4x4 when there's a much shorter one available.
