WebNov 20, 2024 · A finite group G is said to be a fixed-point-free-group (an FPF-group) if there exists an automorphism a which fixes only the identity element of G. The principal open question in connection with these groups is whether non-solvable FPF-groups exist. Web(1) If a finite group acts transitively but not trivially on a set, then some element of the group has no fixed points. You can also use (0) to show: (2) When a nontrivial finite group acts on a set in such a way that every g ≠ 1 has exactly one fixed point, then apart from free orbits there must be exactly one orbit, of size 1.
