v · mathematical field of group theory, the O'Nan group O'N is a sporadic simple group of order    29 · 34 · 5 · 73 · 11 · 19 · 31 = 460815505920 It was found by Michael O'Nan (1976) in a study of groups with a Sylow 2-subgroup of "Alperin type", meaning isomorphic to a Sylow 2-Subgroup of a group of type (Z/2nZ ×Z/2nZ ×Z/2nZ).PSL3(F2). The Schur multiplier has order 3, and its outer automorphism group has order 2. Its triple cover has two 45-dimensional representations over the field with 7 elements, exchanged by an outer automorphism (Ryba 1988). The subgroup fixed by an outer automorphism of order 2 is the Janko group J1, a maximal subgroup. O'N is one of the 6 sporadic simple groups called the pariahs, because they are not found within the Monster group. References O'Nan, Michael E.
