This is called its kaleidoscopic\ngroup. We reframe the construc tion in terms of countable structures\nand determine which dynamical prop erties are preserved when passing to\nthe kaleidoscopic group. This requi res a novel structural Ramsey\ntheorem and produces a new class of example s exhibiting a poorly\nunderstood phenomenon\, namely non-metrizable univ ersal minimal flows\nwith a comeager orbit. \n\nThis is joint work with T odor Tsankov.\n\nMC 5479\n DTSTAMP:20230531T211942Z END:VEVENT END:VCALENDAR
