These are (1) 1 edge oriented wrong and (2) a wrong permutation of 2 edges.Then, remember how to solve the 3x3 Rubik's Cube, because it's pretty similar from here on. You don't need to learn any new tricks for this, you just have to be more careful.

Generally you can't recognize it until you are a Parity/ edge paring algs for 4x4/6圆. I used the 4x4 algorithm: Parity 2 (1 flipped edge) With edge in front: 2R* 2B 2U L* 2U R'* 2U R* 2U 2F R* 2F L'* 2B 2R* The second parity is a 2 edge swap parity. When forming the edges you only have a 50-50 chance of creating a cycle amongst those edges that has the same parity as the corner permutation. Look at the r slice right before the r2 turn. A way to solve more complex Rubik's Cubes is accomplished through using what is commonly called the 3x3x3 reduction method. How to fix the corners of a white cross in 4x4 cube, if the colors. If your algorithm does mess up centers, you can always just fix the edges with the r r' algorithm, which is completely center-safe.Generally you can't recognize it until you are a F l B L2 B' l' B L2 B' F' l' D2 U2 r' D2 U2 l' d2 l2 d2 also swaps edges UFl and UBl.
