Canonical


The word canonical is used to indicate a particular choice from of a number of possible conventions. This convention allows a mathematical object or class of objects to be uniquely identified or standardized.

For example, the right-hand rule for the cross product is a convention, which corresponds to the canonical vector space orientation in R^3. Similarly, canonical labeling provides a way to uniquely label a graph so that isomorphism checking is reduced to comparing canonical labelings of two graphs.
