\(nX\)-complementary generations of the Harada-Norton group \(HN\). (English) Zbl 1110.20300
From the text: Let \(G\) be a finite group and \(nX\) a conjugacy class of elements of order \(n\) in \(G\). \(G\) is called \(nX\)-complementary generated if, for every \(x\in G-\{1\}\), there is a \(y\in nX\) such that \(G=\langle x,y\rangle\). The question of finding all positive integers \(n\) such that a given non-Abelian finite simple group \(G\) is \(nX\)-complementary generated was posed. Here we answer this question for the Harada-Norton group \(HN\).
