How many steps on $S_n$ are required to span $V\wedge V$, $V = K^n$?
Let $A$ be a set of generators of $G=S_n$; assume $e\in A$,
$A=A^{-1}$. Let $V = K^n$, $K$ a field. Consider the natural

Regular elementary abelian subgroups of primitive permutation groups
A finite group $B$ is said to be a B-group if every primitive permutation group having a regular (transitive) subgroup isomorphic to B is $2$-transitive.
Schur proved that a cyclic group of ...
