We consider words coding exchange of three intervals with
permutation (3,2,1), here called 3iet words. Recently, a
characterization of substitution invariant 3iet words was
provided. We study the opposite question: what are the morphisms
fixing a 3iet word? We reveal a narrow connection of such
morphisms and morphisms fixing Sturmian words using the new notion
of amicability.
