Twists and Flips
A corner at a certain place can have three states. Algorithms that take a corner from one state to another twists a corner. For pratical reasons, twisting is considered undefined when a corner does not stay at the same place. Mathematically, twisting can still be defined, but only in a less intuitive way of little concern to us.
When viewed from the exterior toward the corner, a clockwise twist of 120° is called positive (e.g. URF ? RFU, or simply X ? X+). Twisting in the opposite direction is called negative (e.g. URF ? FUR, or simply X ? X). Note that X++ º X, and X+++ º X.
An edge at a certain place can have two states. Algorithms that take an edge from one state to another flips an edge. Flipping is considered undefined when an edge is moved to another place. An example of flipping is UR ? RU, or simply X ? X+. Note that X++ º X.
