Edges are labelled from right, up, left and down E, F, G, H

circular edges clockwise F fixed

	M2 U' M U2 M' U' M2

circular edges counterclockwise F fixed

	M2 U M U2 M' U M2

Memorization: (M2 U' M) U2 (M' U' M2): M2 M M' M2 interwoven with U' U2 U'

Memorization: (M2 U M) U2 (M' U M2): M2 M M' M2 interwoven with U U2 U (U is opposite of the previous one)

2 pairs or edges are swapped, opposite (forming a cross) or adjacent (forming 2 parallel slash).

swap EF and GH
