• Abstract:
  An infinite linearly ordered set (S,\leq) is called doubly homogeneous if its automorphism group A(S) acts 2-transitively on it. We show that any group G arises as outer automorphism group G\cong{\rm Out}(A(S)) of the automorphism group A(S), for some doubly homogeneous chain (S,\leq).
