5x5 Edge Parity Question

[monte cristo]

Hello, - Long time cuber, and message board viewer, but I've finally reached an impasse (after 3mo. of trying). need some guidance.

I've intuitively solved this cube up to this point, cannot find anything on this 2 edge parity configuration. Any ideas?

If that isn't a Z-perm. You can't solve it. This is a odd layered cube, so at the 3x3 stage there's no parity.

Unless you have a z-perm, that case isn't possible because you have a 2 swap of inner edges. It's like if you had a 2 swap of edges on a 3x3 because the corners and inner layer edges act like a 3x3. You can solve the wings though: just use k4 or some other comms based LL method.
