Abstract

We show that the sporadic simple group \M(22)\M(22), the exceptional group of Lie type 2\E6(2){}^2\E_6(2) and their automorphism groups are uniquely determined by the approximate structure of the centralizer of an element of order 3 together with some information about the fusion of this element in the group.
