A display of a topological group G on a Banach space X is a topological isomor- phism of G with the isometry group Isom(X,jjjjjj ) for some equivalent norm jjjjjj on X, where the latter group is equipped with the strong operator topology. Displays of Polish groups on separable real spaces are studied. It is proved that any closed subgroup of the innite symmetric group S1 containing a non-trivial central involution admits a display on any of the classical spaces c0, C((0,1)), lp and Lp for 1 6 p < 1. Also, for any Polish group G, there exists a separable space X on which f 1,1g G has a display.
