A permutation group G on a set Q has a natural action on Q for each natural number n. The group is called oligomorphic if it has only finitely many orbits on Q for all «GN. (The term means "few shapes". Typically our permutation groups are groups of automorphisms of structures of some kind; oligomorphy implies that the structure has only finitely many non… CONTINUE READING
