Hello everybody!

http://www.youtube.com/watch?v=j0rIyQUj52o

In this video I showed different variants of permute the central elements on the big cubes.

I used modification of algorithm r U' l' U r' U' l U (see step 6 in http://www.speedsolving.com/wiki/index.php/Cage_Method)

Can to somebody this will interesting.

And I will be glad if who shows other ways for permute of the centers.

Good job if you came up with that on your own, but basically this is just normal commutators for center pieces.

Thanks!
Yes, some variants I received as a result of my practice, for example, the permute of centers from 3 sides.

There is an algorithm that I came up with based on the corner flip algorithm: [(r' u r u' or r u' r' u), (U, U', F, F', R, or R')]. This acts as a three cycle between two colors, so it is almost the same as your algorithm, but it can be done 12 different ways instead of 2, so it will be slightly more useful, but less efficient. So overall, the two algorithms are about equal.

Yes, if to look narrowly, all this is based on the commutator [x, y, x', y'] with intermediate moves:
l' U r U' l U r' U'
l' U' r U l U' r' U
r2 f2 r2 f2
l2 U r2 U' l2 U r2 U'
U r2 U' l' U r2 U' l
b D' l' D b' D' l D
(l' r u l r') U2 (l' r u' l r') U2
