Clone

Summary

A clone on a set AA is a set of finitary operations on AA that contains all projections and is closed under composition. The term operations of any algebra with universe AA form a clone, and every clone arises in this way. Clones let one compare algebras by what they can express, regardless of which basic operations were chosen. Two algebras on the same set with the same clone of term operations have the same subalgebras, congruences and automorphisms.
