Abstract

Let mnm\leq n be positive integers and X\mathfrak X a class of groups which is closed for subgroups, quotient groups and extensions. Suppose that a finite group GG satisfies the condition that for every two subsets MM and NN of cardinalities mm and n,n, respectively, there exist xMx \in M and yNy \in N such that x,yX.\langle x, y \rangle\in \mathfrak X. Then either GXG\in \mathfrak X or G(18053)m(n1).|G|\leq \left(\frac{180}{53}\right)^m(n-1).
