The Small index property for countable 1-transitive linear orders

Abstract

It is shown that the countable saturated discrete linear ordering has the small index property, but that the countable 1-transitive linear orders which contain a convex subset isomorphic to 2 do not. Similar results are also proved in the coloured case. 2000 Mathematics Subject Classification. 20B27, 06F15.
