An algebra A is finitely presented if there is a finite set G of generator symbols, a finite set O of operator symbols, and a finite set Γ of defining relations xΞy where x and y are well-formed terms over G and O, such that A is isomorphic to the free algebra on G and O modulo the congruence induced by Γ.
