Almost all finite groups are $2$ -groups of class two

Ning Su, Binzhou Xia

We prove that almost all finite groups are $2$ -groups of nilpotency class two, when groups of order at most $x$ are counted up to isomorphism and $x \to \infty$ . More precisely, unif…

Which maximal subgroups are perfect codes?

Shouhong Qiao, Ning Su, Binzhou Xia +2

A perfect code in a graph $Γ = (V, E)$ is a subset $C$ of $V$ such that no two vertices in $C$ are adjacent and every vertex in $V ∖ C$ is adjacent to exactly one vertex in $…
