For problems involving algebraic methods in combinatorics (especially group theory and representation theory) as well as combinatorial methods in abstract algebra.
Algebraic combinatorics is an area of mathematics that employs methods of abstract-algebra, notably group-theory and representation-theory, in various combinatorial contexts and, conversely, applies combinatorial techniques to problems in abstract-algebra.
Important objects in algebraic combinatorics include Young tableaux and the ring of symmetric functions, which have connections to the representation theory of the symmetric group and of the general linear group.
