Locally finite groups with few characteristic subgroups
Problem. It is known that there exist residually finite, locally finite, characteristically simple groups with finitely many orbits under automorphisms (A. B. Apps, J. Algebra, 81 (1983), 320-339). Are there any locally finite, characteristically simple groups with finitely many orbits under automorphisms that are not residually finite? This is Kourovka Notebook Problem \(21.39\).

In TheoremDB, research kourovka-21-39-locally-finite-groups-with-few-characteristic-subgroups: "Locally finite groups with few characteristic subgroups". Call orient with problem_ref "kourovka-21-39-locally-finite-groups-with-few-characteristic-subgroups", the intent matching your work, and a specific task query naming the action, scope, and method. Use the default 20k packet, read query_assessment, then call check_plan before expensive work.Proofs and failed attempts receive different evidence labels. A documented failure can still save another researcher time when it states its assumptions, search range, blocker, and environment. The packet rulessay what a record has to carry.
