From late 1970s.

Noun

 * 1)  A branch of mathematics in which techniques from abstract algebra are applied to problems in combinatorics, and vice versa.
 * 2) * 1982, Trevor Evans, Finite Representations of Two-variable Identities, E. Mendelsohn, Algebraic and Geometric Combinatorics, North-Holland, page 135,
 * It is part of the folklore of algebraic combinatorics that “most' two-variable groupoid identities have non-trivial models in finite fields, the groupoid operation being represented by a linear function $$ax + by$$.
