## OH COLL

These are the 40 corner cases for the last layer when the edge orientation is correct and the one-handed algorithms I use for them. Note that I do not use COLL for the Sune or Antisune cases, so I have not included one-handed algorithms for these cases. These algorithms appear EXACTLY as I perform them when I am solving the last layer, in speedcubing notation with rotations included in the algorithm. It should be noted that these are the algorithms that I find easiest to perform. However, you may find other algorithms better-suited for your own hands, so it is recommended to try many different algorithms for the same situation to find which one works best for your own style of cubing.

In each diagram, yellow is the color of the upper face. A yellow "bar" indicates that the last layer color is facing that direction in that location. Another color denotes that a particular piece is not oriented correctly. If a sticker is colored grey, it is not important for recognition. For recognition, we will consider red the front, orange the back, green the right, and blue the left. Mostly we will just be looking to see which pieces match or are opposite from each other, so the exact color is irrelevant. We're just looking at how pieces are arranged relative to each other.

In each diagram, yellow is the color of the upper face. A yellow "bar" indicates that the last layer color is facing that direction in that location. Grey denotes that a particular piece is not oriented correctly.
