4x4 makes me nervous

[xyzzy]

So in this particular case where the 4x4 is solved except for 2 corners on the same face, would I do (in a 3x3 sense) a T perm to swap the corners and then do some edge perms to correct the now incorrect edges? No wait, I'd still have only 2 edges to swap which is a 4x4 specific alg I think. I don't think you could ever have only 2 edges out of place on a 3x3.

Is that right?

Yup.

This is a PDF i created years ago for parity. You can use them on really any big cube with slight modifications because of cube size.
