The twisted automorphism group of a structure is the normalizer in the full symmetric group of its automorphism group. Following Cameron and Tarzi, we ask when the group of twisted automorphisms splits over the group of automorphisms. After explaining their result for the case of randomly edge colored infinite complete graphs, we discuss joint work with Rebecca Coulson which answers this question in the case of metrically homogeneous graphs.
