Query: Combinatorial Hopf algebras from representations of families of wreath
  products   We construct Hopf algebras whose elements are representations of
combinatorial automorphism groups, by generalising a theorem of Zelevinsky on
Hopf algebras of representations of wreath products. As an application we
attach symmetric functions to representations of graph automorphism groups,
generalising and refining Stanley's chromatic symmetric function.
