Line 7:
*A [[complete set of invariants]], together with which invariants are realizable, solves the classification problem, and is often a step in solving it.
*A computable [[complete set of invariants]] (together with which invariants are realizable) solves both the classification problem and the equivalence problem.
* A [[canonical form]] solves the classification problem, and is more data: it not only classifies every class, but givesprovides a distinguished (canonical) element of each class.
 
There exist many '''classification theorems''' in [[mathematics]], as described below.
