Query: Automorphism Groups of Countably Categorical Linear Orders are Extremely
  Amenable   We show that the automorphism groups of countably categorical linear orders
are extremely amenable. Using methods of Kechris, Pestov, and Todorcevic, we
use this fact to derive a structural Ramsey theorem for certain families of
finite ordered structures with finitely many partial equivalence relations with
convex classes.
