4x4 Corner Parity?

[ballaknight519]

any easier alg. other than r2 U2 Rr2 U2 Rr2 U2?

The one I use is very similar, but that's the only one I'm aware of. Mine's r2 U2 r2 U2 u2 r2 u2. I found it really easy to remember though in general, since all turns are 180 degrees.

corners on front:

z Rw2 U2 R' U2 R' U2 R x U2 Rw2 U2 x' U2 3R U2 R' F2 Rw2 x' D2 R2

something like that.
