| contents | In this paper, we prove that if a finite group acts smoothly and effectively on an integral homology six-sphere and the fixed point set has an odd Euler characteristic, then the acting group is isomorphic to either the alternating group on five letters, the symmetric group on five letters, or the Cartesian product of the alternating group on five letters and a group of order 2 and the fixed point set consists of precisely one point. |
